1. One molecule Buckminsterfullerene has 60 carbon atoms. 2. The two properties of carbon that gives rise to millions of carbon compounds are: Catenation - The property to form long Chains. (Due to its small shell count) Tetravalency - The Phenomenon to form 4 covalent bond with other atoms. 3. Graphite has 1 free valence electron whereas Diamond doesn't Due to its Structure of the Molecule. Thus the free electron contributes to the ability to conduct the electricity.

Top questions answer is.. 1 ans ----60. 2 ans ---catenation and tetravalancy 3 ans___ because graphite has 1 free electron but diamond does not have any free electron Thanks for this amazing video

1- C60 2- (i) Catenation (ii) Tetravalency (iii) Tendency to form multiple bonds (iv) Isomerism

Happy teacher's day sir 🙏🏻🙏🏻💟

Answers : 1) One molecule of buckminsterfullerene has 60 carbon atoms. 2) The properties of carbon that giver rise to millions of carbon compounds are : catenation and tetra valency of carbon. 3) Graphite is a good conductor of electricity for the reason that it contains free electrons that conduct the flow of electricity, whereas diamond doesn't have free electrons and hence cannot conduct electricity. The video was helpful:)

1.60 carbo atoms 2.catenation and tetravalency 3.because at the four valency electrons, three are used for bond formation and 1 free electron is present

1) There are 60 Carbon atoms present in one molecule of Buckminsterfullere.(C60) 2) Followings are the 2 properties of Carbon: (1) Carbon has 4 atoms in its outermost shell ( valence shell), it is difficult for Carbon to either donate 4 electrons or to gain 4 protons to become a stable atom. That's why it shares its elements, and so called Tetravalent. (2) It shows the property of Catenation i.e a property by which a carbon atom can bond with any other number of carbon atoms to form straight chains, branched chains and rings. 3) In Graphite, each Carbon atom is bonded to 3 other Carbon atoms. So, 3 electrons are used in bonds here, 1 electron is free, thus in the whole structure a large number of free electrons are present which makes Graphite a good conductor of electricity. Whereas, in Diamond, 4 electrons are used in Covalent bonds. Thus there are no free electrons. Hence, it does not conduct electricity.

1. - 60 carbon atoms in one molecule of buckministerfullerene 2. - Catenation (Linking of carbon atoms and forming long chains) - Forming Covalent Bond (Sharing electrons) 3. - In diamond all 4 carbon atoms are shared in covalent bonds so there are no free electrons making it a bad conductor of electricity. While, In graphite 3 carbons atoms bonded to other 3 carbon atoms leaving 1 free electrons making it a good conductor of electricity. Hope these answers are correct and I had doubts in this part of the lesson now i am very much clear. Thank you for the clear explanation sir.

1) 60 atoms 2) a. Tetravalent ( valency is 4 ) b. Catenation ( self bonding ) 3) In Diamond one carbon atom combines with four other carbon atoms so all the four atoms involve in bonding but in graphite one carbon atom is attached with three carbon atoms that's why one electron remains free and because of the presence of that free electron the graphite is able to conduct electricity. How Beautifully He Explained The Topic !!✨ Keep going :)

Q1:60 atoms Q2:Catenation and Tetravalent Q3:Graphite has free electrons whereas diamond doesn't

1) 60 atoms 2) -Tetravalency -Catenation 3)Because Graphite has free electrons and Diamond does not have free electrons

Been 4 years since the video has been posted yet it has not failed to prepare many students even today. 2022 - 2023 batch. Thanks a ton Sir cause you're helping us reach the sky with these amazing, informative videos.

1. 60 carbon atoms 2. Catenation= ability to make bonds with other elements tetravalency = carbon has electronic configuration of ( 2,4 ) Hence 4 valence atoms, Therefore it can neither lose nor gain electrons to be stable, this results in carbon making covalent bonds and share electrons instead of losing or gaining 3. graphite is a good conductor of electricity coz it has 1 free electron while diamond has all 4 electrons shared to another and is a bad conductor of electricity

That is a new knowledge for me! Thank u Sir!

Q1 it contains 60 carbon atoms. Q2 catenation and tetravalency property. Q3 diamond doesn't have free mobile electron while graphite have it.

Very lovely explanation sir, 1. 60 carbon atoms. 2. Because, carbon has, catenation and tetravalent propeties. 3. Because, graphite has a bond of three electrons so, 1 atom is always free in the whole bond, that makes it, a good conductor of electricity..... 👍👍🔥🔥❤️❤️ Edit :- A spelling error was there.....😔😔

1. There are 60 atoms present in one molecule of buckminsterfullerene. 2. Catenation and valance of 4 3. Diamond don't have free electrons so they do not conduct electricity But Graphite have free electrons so they conduct electricity

1. 60 carbon atoms will be present as 12 in pentagon pairs and 20 in hexagon pairs. 2.catinaton and travalent property . 3.As in diamond 1 carbon atom is connected with other 4 c atopm so there are no free electrons to conduct electricity but in graphite 1 carbon carbon atom is connected to other 3 c atom so there is 1 free atom in very mokecules hence conduct electricity.

Excellent sir. This video helped me a lot. Way better than how i learnt in school. Nice and fun way. Thank you so much!!

But the Ads are disturbing.

The visual presentation you give is so nice and helpful..it makes us understand clearly..

1} 60 2} Tetravalent and catenation. 3} This is because graphite has free electrons which can conduct electricity and diamond is rigid therefore the electrons are compact.

😊👏👏👏👏👏👍nice explanation..

Most of the student viewed video in lockdown ... 😁😁😁😁😁😁😁😁

Every video we have seen in your RU-vid channel is simple and understandable. We are so much thankful to you

1. 60 Carbon Atoms. 2. Catenation and Tetracovalent. 3. While forming compounds, diamond atoms are compactly arranged and have no free valance electrons while graphite has spaces in it allowing electricity to pass through it, also every C-atom of graphite has 1 free e-.

1. 60 2. Tetravalency and catenation 3. Graphite shares its electrons with 3 other Carbon atoms leaving one electron free. This helps in conduction of electricity. But diamond makes covalent bonds with 4 other Carbon atoms, thus making it completely stable

Ans. 1:- There are 60 carbon atoms present in the one molecule of buckminsterfullerene. Ans. 2:- The two properties of carbon that rise to give millions of carbon compounds are:-- I) Catenation- carbon has a unique ability to combine with other carbon atoms to form long chains, this ability of carbon is knows as Catenation. II) Tetravalency- Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon. Ans. 3:- Graphite is a good conductor of electricity because it has a free electron in every hexagonal structure, but diamond has no any electrons in any structure.

1) 60 carbon atoms 2) 1. Tetravalency and 2) catenation 3) because graphite has free electrons and diamond doesn't have free electrons as they are used up to form bonds.

1) 60 carbons 2) catenation and tetravalent 3) graphite has free electrons whereas diamond has no free electrons

Q.1. 60 Carbon Atoms Q.2.(1)TetraValency,(2)Catenation Q.3.Because,Each Carbon Atom In Graphite Is Bonded With Three Carbon Atom(So Free Electrons Are Present)While In Diamond Each Carbon Atom Is Bonded With Other 4 Carbon Atom (So Free Electrons Are Not Present) And Free Electrons Are Necessary For Conduction Of Electricity Therefore,Graphite is Good Conductor Of Heat While Diamond Is Bad Conductor Of Heat.🌝☺️

✨Answers of last three question--- 1]60 carbon atoms are present in one molecule of buckminsterfullerene✨ 2] (a)Tetravalent✨ (b) Catenation✨ 3] Graphite conduct electricity Because of the presence of free electron and Diamond💎 didn't because it doesn't have free electron✨ Thank you sir...your teaching is just amazing🤩✨✨

Q1=60 Q2= catenation and tetravalent Q3= As electricity passes through the substance having free electrons though graphite has free electrons to pass electric current where diamond hasn't any free electrons to conduct electricity.

Marvellous explanation 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥⚡⚡⚡⚡⚡⚡

so useful video answers are; 1; 60 molecules 2; *Catenation * trevalent 3; As graphite contains many free electrons it is a good conductor of electricity and diamond cannot contain free electrons so it is not a conductor of electricity. the question were also amazing

Q2) Catenation and Tetravalency Q3) because in graphite while forming covalent bonds 3 electrons are used up where as there is 1 free electron ..... free electron is a electron which leaves its atom....... any electron that is not attached to an ion, atom, or molecule and is free to move under the influence of an applied electric or magnetic field. Q1) 60 atoms am i corect sir ????????

1:60 carbon atoms 2: catenation and tetravalency 3:graphites has free electrons while diamond does not have free electrons

Answers: 1. 60 Carbon atoms 2. Carbon is tetravalent and has the ability to form covalent bonds with many elements. It also forms bonds with other carbon atoms and this is known as catenation. 3. Graphite is a good conductor of electricity because in the graphite molecule, 1 atom of Carbon is linked to 3 others; and with Carbon's valency being 3, 1 atom is left. Due to this, lot of free electrons are present and thus, graphite is a better conductor of electricity than diamond.

1.60 carbon atoms 2.catenation and tetravalency properties 3.diamond and graphite are different in physical property ,but same in chemical property

A1. 60 atoms A2. a. Carbon have many compounds because it forms covelent bond b. And it becomes highly reactive on burning. It is a highly reactive element. A3. Graphite is a good conductor of electricity because its one electron in each compound doesn't connect with other atoms. And diamond atoms are closely packed with each other.

C=60 Catenation and tetravalent Because dimond is attached with 4 atom so it has no free electrons But graphite is attached with only 3 atoms to carbon so it has 1 free electron which helps to conduct electricity

May Allah bless u alot sir

1)60 2)tetravalent and catenation 3)graphite is good conductor of electricity due to the presence of free electrons but in diamond there are no free electrons

1:-60 atoms 2:-Tetravalent And Catenation Property 3:-Graphite Has 1 free Electrons But Diamond Has Not

Please make more and more videos because due to your video we are really 'enjoying' study and learning from everyday life Keep it up👍

1. 60 3. In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas In diamond, they have no free mobile electron. That is why diamond are bad conductor electricity

We are a batch of chemistry students from Australia. Thanks for the video! We loved it!

Q1 60 carbon atom Q2 catenation , tetra valent Q3 graphite contains a free carbon molecules due to which it conduct electricity

1. 60 2. Tetravalency and catenation 3. Graphite has many free atoms

Thank you sir for explaining this topic. One doubt sir 05:57 Sir, Alakh Pandey Sir(Physics Wallah) told that in covalent bond the formation of bond is weak whereas you are telling bond of carbon are very strong. Please explain sir🙏

Ans 1: 60 carbon atoms.. Ans 2:Carbon atoms are tetravalent they have four electrons which makes it difficult for carbon atom to either lose or gain electrons so it shares electrons forming a covalent compound this leads to forming millions of carbon compounds. Ans 3:Electricity is the flow of electrons from higher potential differance to lower potential differance as there are no spare electrons in a diamond it is a bad conductor of electricity and as there are many spare electrons in graphite it is a good conductor of electricity.. Enjoyed the video sir... My chemistry journal is complete thanks to you.. Thanks a lot sir...
