Stereoisomerism

You can't play music with stereoisomers but you can earn marks in an exam with them. This video will look at geometric isomerism (aka E-Z isomerism) and optical isomerism. There is also a look at what enantiomers, chiral and racemic means and application to pharmaceuticals.

Good day sir. I self taught myself AS Chemistry and managed to get an A :)
My only source of knowledge, outside textbook, in video format... was your excellent videos on AS Chemistry and revision. I cannot thank you enough... ever! You got me here! May the Force be with you!!!

[@PreSleepASMR]

Heyy I’m just starting AS chemistry can u pls help me I’d appreciate anything

[@armzy4608]

@@PreSleepASMR What do you need help with?

[@stitchinbeeee]

You've explained this so well. Thank you so much for all your videos, they are really helpful! :)

[@AlleryChemistry]

+Ellie Cooper Thanks! Difficult to know if I explain them clearly enough until I get feedback so thanks for that.

[@saadpatel2734]

The model used is perfect for understanding, even a 6-year-old can understand.
Thanks, sir, you have saved my grade

[@oliviaaaable]

Thanks so much, you are a really good teacher! This has really helped me with my access to HE chemistry assignment

[@craig7719]

thanks for all your hardwork honestly changing lives

[@Editz1001]

That model finally makes sense what it means by ‘restricted rotation around the double bond’.
Thanksszxx

[@AlleryChemistry]

You're welcome!

[@sarahsandy2204]

I love your explanations - everything now makes so much sense! THANK YOU!!

[@shackletonkeiditsch4032]

a way to remember i use is if they on the same side, they are on the Zame side. and yh helps a bit.

[@AlleryChemistry]

Sounds a good way to remember!

[@amya8045]

I'm at as level and with aqa we have to do the geometric but not the optical so Thanks this helped a lot

[@lucydawkins4552]

Thank you for these great videos!! You are such a good teacher and they have helped me an awful lot!! :-)

[@iRam8UnderScore]

When given a molecule in a question, how can we tell which branches to draw with wedged or dashed, or normal lines?

[@legendarytaj2054]

Hi i was wondering if you have a video on CIP priority rules for OCR. Thanks

[@alexc87]

love your vids but try and keep the intro sound a bit lower pls

[@oioiyouthere]

Really disappointed that you have not kept the old specifications playlist, trying to find the videos now have been really difficult. Anyways, great videos as usual! Very informative and useful, my exam is in 3 days!!

[@AlleryChemistry]

Good luck with your exams.

[@nefeligeorgiou7016]

big things thumbs up👏🏻👏🏻👍🏼👍🏼

[@roha9424]

Your videos are amazing. Do you cover all the content for Edexcel?
Is there any sites you think are good with practise q's and answers?

[@aymenjahangir9784]

Sir, How can we tell if the double bond in a ring structure is capable of showing cis-trans isomerism?

[@khuloodahmed7216]

Very helpful! Thank you 🙏🏻

[@saramacaron8878]

Hi Sir
Will you be able to answer this question for me please ?
Why is a racemate formed?

[@sakifnewaz7212]

How are there only 9 videos in topic 17 is half the entire A-level textbook

[@sakifnewaz7212]

Chris mate I think there need to be more vids added

[@mysterywoman8158]

Thank you

[@anjalitripathi8706]
