I learnt more in 2 days watching his videos than I did my entire second AS semester. A true legend.

In my second year of uni and i still use these videos to jog my memory haha was a massive help during a levels, cheers..

[MilitaryConnect]

I will make sure you go to heaven for this. Thanks a lot mate.

[corrin]

genuinely owe you my life sir, thanks so much for all your help! i have my paper 2 tmrw, if i get into either of my uni choices it will be all down to you and your videos (even if i'll be studying modern languages when i get there XD) best of luck to everyone sitting the june 2023 exams! xxx

Wish the Internet was this useful when I did my a levels 20 years ago.

[Badflameboy]

YES! This is perfect timing, polymers is the last thing I had to go over.

Thank you for all the vidoes you've made, they helped a lot with Unit 1 & 2, and are certainly helping with Unit 4, looking forward to Unit 5 vids! :)

[mehdik]

Your videos are Fantastic! Thank you so much!
P.S. Can you do a video on Synthetic Routes PLEASE! It really is a challenging topic Thanks!

I'm a bit confused as to what happened to the OH and H in terylene from the middle of the two molecules. I understand what happened at the end but how did you link them with just the O and there wasn't 2 molecules of water

[xHamoodiHD]

have you got any on the amino acids and DNA topic by any chance

[hassanparvez]

At 15:18, shouldn't there be 2H20's to balance?

[haiderfarouq]

When drawing a repeating unit, can you draw it full as opposed to writing  (ch2)4 in the middle?

[giane]

at 12:46 why is it not 1, 4 dioic acid but 1, 4 dicarboxylic ? what is the difference

[fianomeng]

Your videos are very helpful .Thanks alot for uploading them. Can you do an video about A2 unit 4 mass spectroscopy

[ryanbower]

Will you do amino acids? 😎 very helpful video thanks sir 👊🏿

[amazingamirah]

Quick question- why benzene, 1, 4-dicarboxylic acid instead of benzene, 1, 4, dioic acid ? -or is that just the way it is

[samnichol]

Thanks for the very helpful video as always! Could you please please do a video about Acyl Chlorides?? :)

No one will read this bit at 11.18 the water is formed from OH from carboxylic acid and H from alcohol . He did it incorrectly and he said its OH alcohols group plus H from carboxylic acid. This resulted in him drawing the polyester incorrectly too. When he says it didn't matter what side o is on thats the way taught in GCSE and in A level it matters

[ehsaanahmad]

Just Wandering, Under Nylon66, Did you not have to specify the position of the the Dioic Acids (i.e. 1, 6)

[uh]

Very helpful video; thanks! :)
Just one quick question - according to DuPont's own literature, Kevlar is manufactured from 1, 4-diaminobenzene and benzene-1, 4-dicarbonyl dichloride (C6H4(COCl)2), rather than benzene-1, 4-dicarboxylic acid. I know this might be a fairly insignificant detail to be worrying about, but would the former still get the marks in an exam question?
