Oh.. god, I never thought Organic chemistry could make sense... Thanks a ton.

@Leah4sci 5 лет назад

Organic Chemistry is fun! You're welcome :)

I am a fifth year clinical pharmacy student. When I was at the first year i didn't use to like organic chemistry because was very difficult in the peepers and board but you managed to make it so easy and enjoyable I wish all the teachers were like you!!!

Why cant all professors be like you?

@SyedFarhanhaseeb 7 лет назад

and most of them talk to "themselves so polite

@Leah4sci 7 месяцев назад

Aww thanks!

@entrepreneursuccess565 4 года назад

so good yes! no certain lucky oxygen gives two electrons to nitrogen, it is because all oxygen are equal, so everyone have the chances to give electron and the pai bound is hanging over the entire molecule because there are some free electrons. great professor many thanks

@IIOXIDIZEII 6 лет назад

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies

@Leah4sci 6 лет назад

@chemistchemist228 6 лет назад

I got question: How can I make synthesis of some molecule because of resonance? If all molecules resonate then which one is the correct structure as end-product of my intended compound? Or even - example aspirine molecule - if Im looking to wikipedia or search in google then I found many different versions or my intended compound so how can I something do and make a synthesis if these molecules are resonate all the time?????????? Kind Regards.

@Leah4sci 5 лет назад

I'm sorry, but I don't offer tutoring through RU-vid comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join

@narutouzamaki4765 Год назад

At 4:17 you said that carbon will have a negative charge, but wouldn't that violate the octect rule?

@Leah4sci Год назад

The molecule at 4:17 does not have a carbon atom. This is the example of nitrate. Every atom in each of my resonance structures is following the octet rule. There are no violations.

@neelkhare6934 6 лет назад

i have a doubt in that cyclohexane example how can the carbon at the bottom have a lone pair the octet is not complete

@Leah4sci 6 лет назад

at which point in the video?

@thebeatles9 9 месяцев назад

FYI the rhinocerus is from Bruice not your student

@Leah4sci 8 месяцев назад

I'm not familiar with Bruice, are you saying this is the source of the rhino mnemonic?

@thebeatles9 8 месяцев назад

p323 in the latest 8th edition@@Leah4sci "The following analogy illustrates the difference between resonance contributors and the resonance hybrid. Imagine that you are trying to describe to a friend what a rhinoceros looks like. You might tell your friend that a rhinoceros looks like a cross between a unicorn and a dragon. Like resonance contributors, the unicorn and the dragon do not really exist. Furthermore, like resonance contribu- tors, they are not in equilibrium: a rhinoceros does not change back and forth between the two forms, looking like a unicorn one minute and a dragon the next. The unicorn and dragon are simply ways to describe what the actual animal-the rhinoceros-looks like. Resonance contributors, like unicorns and dragons, are imaginary. Only the resonance hybrid, like the rhinoceros, is real."

@JohnVKaravitis Год назад

I thought that resonance did NOT mean that electrons were "constantly moving back and forth, back and forth". Resonance = electron democratization, and shows relationships, not actual movement.

@Leah4sci Год назад

I'm not sure I understand, what is 'democratization?' Without getting too technical (advanced physics) the simple way to understand resonance is to think of the electrons moving or 'resonating' back and forth

@violettalt2257 Год назад

Is formal charge the same as the partial charge?

@Leah4sci Год назад

They're very very similar. Partial charges could be attained through resonance, but formal charge is speaking of something very specific to a single atom, as drawn in a particular Lewis structure. For my formal charge formula and shortcut, make sure to read my tutorial at Leah4sci.com/Formal

@violettalt2257 Год назад

@@Leah4sci Thank you very much, your video gave me a slight hope to my organic chemistry 2 lesson. It's little bit hard because we haven't learn the organic chemistry 1, but i am trying to catch up by watching your video ❣️

@emilius_525 Год назад

Why does Nitrogen have a positive charge?

@Leah4sci Год назад

In the case of the nitrate ion, the nitrogen has four bound electrons and no lone pairs of electrons. According to the equation for formal charge, that's 5 valence electrons minus 4 bound electrons equals a formal charge of +1. For more on formal charge, make sure to see my tutorial at Leah4sci.com/formal

@Geezweez788 2 года назад

So resonance is actually fluidity. Fluidity creates an intramolecular communication network which inturn creates molecular self awareness. If there is fluidity then there are no still electrons, all electrons are moving with each pair of electrons having a turn to go in to form the double bond.

@Leah4sci 2 года назад

Yes, resonance is the idea that certain electrons can be delocalized and are allowed more freedom of movement across a molecule.
