A few misleading things in this video. First of all a lot of the structures are not great: molecular geometries were wrong for sulfuric acid and H3O+, and there-s the tendency to show square-planar-type structures for organic molecules - obviously people do this for the purpose of teaching, but then when you want to show a mechanism, e. g. an elimination, you need to introduce another method of representation for it to make sense. Speaking of which, the reversible hydration/dehydration would surely give the E alkene as the major alkene component, very quickly. As presented in the video, it makes it look like you would have a mixture of the Z alkene and the alcohol, which effectively would not be true. Also the reference to pKa was quite odd: why state that the protonated alcohol has a low pKa if it-s not going to be compared to H3O+ in the forward direction?

Thank you for the video. Have you ever considered creating a course oriented more towards mathematics? I am an avid fan of your videos, but often have to turn to other resources for mathematical help.

omg you're such a good teacher. I've already had all my org chem classes and I still don't understand a lot of the basic stuff. My teachers actually didn't bother to teach us this: /

11: 45 I loved the phrase -Don't panic- that makes me remember the cover of Hitchhiker guide to the galaxy book. Like if you read that awesome book. Nice content. Leave my like.

Organic reactions tend to proceed to give multiple products. Usually one of. the products is a polymeric material often called tar.

You lost me at electrophilic additions of a protein to an alkaline.
I need to go back over my high school chemistry lol

Soooo gooood! Can you show us elimination of N2 form amines (by HNO2). I thinks that it s very interesting reaction. Good luck
