These videos are brilliant - clear, concise and well illustrated. They include great tips and examples. I am able to understand the topics and help my son. Thank you👍🏼

[@Cognitoedu]

Glad you like them 😊

[@T16650]

Thank you so much! We weren’t taught this topic because of lockdown, but my mocks (which we were just recently warned about- Thanks Boris!) are in a week, this is life saving!!!

[@Cognitoedu]

Thanks T T, lockdown sucks but good luck with your mocks!! 🤞

[@madeleinej6048]

How do you do it…?! How do you help loads of people pass their GCSE’s by making amazing educational videos that aren’t just easy to understand but also explain a whole hours worth of a lesson in 5 minutes still with enough detail. I’m honestly amazed at how far I’ve come just going through my curriculum on your website. I actually look forward to revising now and as I’ve got my GCSE’s coming up this May I know I need to knuckle down but as long as I’ve got this dude i know I’ll pass no question. Thank you so so much 😊

[@Cognitoedu]

Ah thank you so much Madeleine 🤩🤩 We wish you the best of luck with your exams!

[@gothmajesty1976]

I just wanna inform you that your videos have been extremely helpful to me and to others as well.

[@Cognitoedu]

Thanks Rahul glad it helped!

[@alex6588]

could you not draw out poly ethene while having just one carbon and two hydrogen atoms per repeating unit? and then have 2n to the right of the bracket instead of n. or is there some sort of rule that prohibits this?

will you get told which monomer it is/ the name of the monomer when writing out tht equation?

[@shauvik_das]

nicely explained thank you very much

[@valent9260]

Does polymerization happen by involving other substance? Or it happen automatically when same monomers meet each other?

[@rab3795]

It does not need another substance to happen. Monomers (addition) have bonds that break open. There are now electrons willing to make bonds with anything. If they meet more monomers like theirs they are going to bind.

what do you mean by 'unsaturated'?

[@reemwaleed2802]

meaning that they have a carbon -_ carbon double bond . The term "unsaturated" means more hydrogen atoms may be added to the hydrocarbon to make it saturated

[@madeleinej6048]

Unsaturated means that the carbon has a double bond (which is when it has the two lines in the middle of both the carbons) and this is what makes it an alkene. Saturated means that the carbon has a single bond which is what would make something an alkane-hope this was explained alright?
