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!!!!
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 :)
I have never loved a video at a firs view before. I love you so much thank youuu!!! Btw I have an exam in less than 9 hours and its 11pm so this is a life saver.💗💗💗
If you’d like to practise what's covered in this video, check out the lesson on the Cognito platform - cognitoedu.org/coursesubtopic/c2-gcse-aqa-h-t_7.09. The platform’s totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

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!!
@@sammh.8578 A hydrogen halide is usually a halogen based acid. Such as HCl or HBr (not to be confused with HBrO3). Thus, its reactions would be different than those of normal halogens. One is a halogenation reaction and the other is a hydrogen halide reaction. Hope it helped!
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.
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
Bro you need at least a million subscribers for this content
Aha thank you mate, maybe one day 🤞
honestly
Let's hope to get 1 million 💜💜💜💜💜💜💜

Thanks Sam! Amadeus and I spend a lot of time working how best to show stuff, so it’s really good to hear they’re useful 🙌
Why is this underrated? This is helpful. It may be short but it is concise! Good for having a brief background of chemistry subjects!
It definitely is underrated.
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
Great to hear it helped! Good job your friend 🤝
You literally can't get a better explanation for this. Thanks!
did this in class yesterday and I didn’t understand it one bit until this vid😁
Yeye je
Yeye je
Icl Cognito is just different
even though i am giving GCE it is still really very helpful. Literally covers up everything. BRAVO
Glad it was helpful Aimen 👍
just found your channel and wow! these are some well made videos!
Fantastic videos. Your videos are the best educational ones I have found. Thank you.
Thanks Marion!! 😊
I’m cramming for mocks and this is saving my life
Bro u r literally indescribable … well done 👏🏻 👍🏻
this channel is saving my boards class 10
instantly subscribed
You are the best teacher I had ever met

Is this aqa?
@@riffatshahnaz5234 idk, but it's free... so....
I have a test tomorrow, thank you for saving my life
Good luck Caavery! 🤞
I am so shocked your videos are legendary! You will get more subs I am sure . Keep the amazing work Mate !
You are the best , FACTS !
Aah thanks mate, it's really great to receive comments like this 😁
thanks man this was helpful!
OMG THIS IS SUPER HELPFULL

Hey, you're right about the conditions, but isn't the bromine reaction also one of the hydrogen halide reaction?

yes but that's not in the GCSE syllabus
this video is for GCSE chemistry and it wouldn't make sense to put that in there as we're not taught that at GCSE
For all those who don't know, hydrohalogenation IS in the IGCSE syllabus!
@@sammh.8578 this is AQA GCSE not IGCSE
you don't have a video lesson for the reaction of alkynes? btw, thank you so much for this.
Alkenes are a homologous series of hydrocarbons that contain only carbon and hydrogen atoms with double bonds.
Is this correct?
i think its best to specify that they are carbon double bonds to spare any confusion
@@ahmedshaeemmohamed1286 thank you very much!
Alkenes are unsaturated meaning they have a carbon to carbon double bond make sure u say that they are also more reactive than alkanes
I have watched up to 12 UA-cam videos to understand this topic, but this was the only beneficial one. Thank you very much 🤩🤩💕
Thanks Mariam we're glad it helped 🥳
Please can you explain the alkynes?
alkanes* and he has a video on it
@@Milojs7it's alkynes
@@Milojs7he don't have a vid on alkynes
THANK YOU SO MUCH. MY EXAMS ARE IN 2 WEEKS AND THIS VID HELPED ME A LOT ❤
1:05 thanks for that woota man nice vid 👍

Thanks for the amazing content. It’s helping a lot for the gcse’s
Thank you very much Arnav 😊
How were bromine and ethene in liquid form?
Thanks for the help, keep it up
Animations are so cute, thank you 🙏
Glad you liked them Ahmet!
good video
blud saved me from failin gcse's
You are my saviour 🙏
Greetings! Do you have transcript of this video?
Your an absolute legend 💯💯
Cmon 11A3 let’s go boyssssss
wag wan g
Can u add the additional molecules anywhere?
Yes
Thank you for saving me♥
you're class mate!
Is this channel also for gcse?
For o levels?
It's for GCSEs as said in title
Is this higher or foundation
Higher
please, please, please do a level chemistry videos!!!!
such a nice video.
What are the products formed when Bromine Water reacts with 2-methylpropene ?
This man is sooooo underrated he deserves at least a million subscribers please
not even a k subs
thanks
the voice is trippy
Thank you🥹
i am in dae college which i study in organic please prepared her lecture and send me if at possible in urdu otherwise i understand english
Good
thx
