Stereoisomerism 

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!!!

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

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

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

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

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

Brilliant video! Thank you so much.

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

My Chem AS is next week and this helped me a lot, Thank you!

Sir you are very competent person ........ Nice explanation .. thanks alot

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

Thank you so much for all of your videos, they are so so helpful. You are such a good teacher!

Your videos are so great .. thank you so much..it is so helpful..may God bless you

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!!

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

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?

What about the lone pair of electrons?are they regarded as a group attached or not?

Thank you!!!!

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

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

Thanks very much.

Vry gudd

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

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

Thanks

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

sir do 1-methyl 3-cyclohexene will be optical active or not?

I love your vids, but i recommend reducing the gain

what taking Sir....
