this guy is an angel

6:52 priceless!!!!

[83oday]

his lectures are really useful

[dadarkvador24]

U Sir sud get a noble prize!!!

all my lecturers litterly suck at teaching and u Sir has made a difference between pass and fail

[red13redc]

He needs to be my prof!! WHERE DO YOU LIVE!! lol

this guy is so funny

I liked your video very much.

One of the most valuable features of the diels-alder reaction is tat the reaction is stereo selective - that is, it referentially forms one stereoisomer over another. with a disubstitued dienophile, if th two substituients on the dienophile start , cis they end up cis in the product, if they start trans, they end up trans in th poduct.

@monicab1alej at 5:52 you can hear him explain what the s- stands for and why it's being used. it's funny how you didn't catch that, haha...

@monicab1alej forget about the answer, he answered it in the video ;)
