GCSE Chemistry - Addition Reactions of Alkenes #55 

This is hands down, the best channel for IGCSE!!!! Let's all take a moment to appreciate the animations which makes it a hell lot easier for us to visualize. Thanks Cognito!!!!

Bro you need at least a million subscribers for this content

Why is this underrated? This is helpful. It may be short but it is concise! Good for having a brief background of chemistry subjects!

this was literally the only thing that was able to actually teach me addition reactions

couldn't understand this topic till months until yesterday when my friend referred this channel to me

You literally can't get a better explanation for this. Thanks!

A ginormous thank you to all the people involved in the making of these videos, you are literally saving millions of students' scores everywhere, including my own lol. I've recommended this channel to my classmates and let's just say my chemistry teacher was finally pleased with the statistics this year :)

just found your channel and wow! these are some well made videos!

did this in class yesterday and I didn’t understand it one bit until this vid😁

Thank you so much for all you do.

Fantastic videos. Your videos are the best educational ones I have found. Thank you.

thanks man this was helpful!

Thanks for the help, keep it up

OMG THIS IS SUPER HELPFULL

Your an absolute legend 💯💯

you're class mate!

this channel is saving my boards class 10 instantly subscribed

You are my saviour 🙏

1:05 thanks for that woota man nice vid 👍

you don't have a video lesson for the reaction of alkynes? btw, thank you so much for this.

such a nice video.

even though i am giving GCE it is still really very helpful. Literally covers up everything. BRAVO

good video

Thanks for the amazing content. It’s helping a lot for the gcse’s

Animations are so cute, thank you 🙏

thx

I have watched up to 12 RU-vid videos to understand this topic, but this was the only beneficial one. Thank you very much 🤩🤩💕

I have a test tomorrow, thank you for saving my life

Greetings! Do you have transcript of this video?

Good

please, please, please do a level chemistry videos!!!!

Hi the contents of the video are wonderful and i used this video for my students in grade 9.But i have a note ,in our curriculum in Lebanon we have one more idea in addition reaction of Alkene which is the addition of hydrogenhalides its name is hydrohalogenation. So if you can make some changes in this video to add the last addition reaction (hydrohalogenation) then it will be perfect for my students.

How were bromine and ethene in liquid form?

THANK YOU SO MUCH. MY EXAMS ARE IN 2 WEEKS AND THIS VID HELPED ME A LOT ❤

Hi, i have GCSE in less than a month but i have never really learned the science syllabus i am trying to do it by watching. but everyone also says do past papers to get familiar with exam style questions. i really need some help or some advice on how to get a solid grade in combined science. thanks cognito

You also forgot to talk about the reaction of addition of hydrogenhalide. which is adding a hydrogen halide to an alkene to form a haloalkene. for example: propene + hydrogen chloride ---> chloropropene. The hydrogen will bond to one carbon and chlorine to another one. we can change the chlorines location to make different izomers which are compounds having the same molecular formula but different structural formula. Like (1-chloropropene and 2-chloropropene). Also in some past paper questions for Chemistry IGCSE (0620) i found that they asked for the catalyst and conditions, so ill list them out. Hydrogenation Reaction Conditions: Catalyst: Nickel Temperature: 150 degrees C Hydration Reaction Conditions: Catalyst: Phosphoric Acid - H3PO4 Temperature: 300 degrees C Pressure: 60 A.T.M Other than that great video. Keep up the good work!!

blud saved me from failin gcse's

Alkenes are a homologous series of hydrocarbons that contain only carbon and hydrogen atoms with double bonds. Is this correct?

Can u add the additional molecules anywhere?

wait but why isn't there a "see you next time" 😅

What are the products formed when Bromine Water reacts with 2-methylpropene ?

Please can you explain the alkynes?

❤

Cmon 11A3 let’s go boyssssss

Is this higher or foundation

Is this channel also for gcse? For o levels?

the voice is trippy

my goat walah

Wow😱

This man is sooooo underrated he deserves at least a million subscribers please
