I get to exam time and struggle for a bit before finding a leah4sci to explain the difficult concepts to me like I'm a human being instead of a robot. I have had such a hard time getting professors to explain things like I do not have a phd in chemistry. Like I understand you look at that thing and just know what is what, but I don't feel like I should have to go out of my way to get an explanation of which carbon is which during class. my goodness, thank you. If I ever get into medschool I'm sending you a card.

Leah, you've helped me so much over the last year. Today is the day before the final in ochemII. I was really nervous and was in my professors office today talking about how worried I was. I came home to do my homework and was still so confused. But this video just calmed me down so much. Thank you for the amazing lesson. I never comment but I just really wanted to say thank you! I really appreciate how much work you put in to your channel and website. You are my favorite online Ochem tutor! The way you explain things is always on my level. Thank you a million times.

The direction of the arrow in the video at time 3:26 is clockwise. If I reverse the direction to counterclockwise but the final product remains the same, does it mean I am representing the mechanism incorrectly (i would love to know)

@Leah4sci

It's a cyclic mechanism which means the electrons are all moving at the same time. No, it wouldn't be wrong

Additionally, why did you break the double bond between C3 & the oxygen group of the dienophile but carried it over into the reaction with the double bond at b?

@Leah4sci

I did not attach a hydrogen to the oxygen atom. Rather, I drew in the hydrogen of the aldehyde as it is understood to be connected to the carbonyl carbon.

why do they call it electron donating and electron withdrawal groups? the electron donating in turn is receiving electrons from the withdrawal group and obviously the withdrawal groups is giving its electron s from its pi bond to the electron donating (diene) group?

When you add heat into a system, you provide enough energy for the molecule to adopt less than favorable conditions including temporarily breaking pi bonds / resonance. During this time the diene can reform into s-cis or s-trans

One does not have to have some kind of degree in "any" subject to teach it. These are just tutorial courses moron !!
