    I've learned more in 3 hours of video lectures UA-cam than i ever did in biochemistry class thank you khan academic and whoever invented technology and UA-cam.

    Your organic chem course videos are really good, there is only one thing that might improve the course and that would be to give practice problems like you do on your other courses not just videos. The videos are phenomenal but giving practice would also be very helpful to solidify these concepts and lock them in.

    I can't ever thank you enough for taking the time to explaining these things with colors, I'm such a visual person that I can't see things if step by step aren't told. Thank you a million and 1 times!!! I will for sure be sharing this video with the rest of my classmates from O. Chem!

    i did not understand the chair flip before, but after you color coded the parts of the cyclohexane it was easy! Great way of thinking about it and teaching it. Thank you!

    They require about 11 kcal/mol of thermal energy. The room temperature has 20 kcal/mol of thermal energy, therefore they change the conformation rapidly back and forth at room temperature.

    Ok so I love your videos but. . . jus a simple correction or question.Isn't Axial C-H bonds parallel to the "axis" of the ring and the Equatorial C-H Bonds project outwards from the ring around its "equator." ?!! I Think u mixed it up in video ^_^ Correct me if I'm wrong. Thank you

    I am tired. I can't find any of the animation kind of videos that what bonds are actually rotating. All I see is just forms drawn before the rotation and forms drawn after the rotations. Seems like no one out there actually knows how these take place basically?
