[@lexrae2729]

Chad is rad. Chemistry makes me sad but Chad makes me glad. Because of chad, I'm gonna be a college grad. Thank u Chad.

[@ChadsPrep]

Your rhymes make me glad, not sad, nor mad but happy for the future rad-glad-lex rae-grad!

[@a.od-reszki4674]

What a poem

[@tamarinds]

God bless you Chad. I've been telling all my fellow Organic Chemistry students about your channel. I think my favorite thing about your channel is that you go section by section! That is unbelievably helpful. Thank you

[@ChadsPrep]

Glad the channel is helping you - Thanks for telling folks about us. Happy Studying!

[@angelteixeiradasilva1293]

I hate how you don't pop up at the top of youtube searches, but I managed to find one of your videos and am glad to be back. You explain these concepts so well and they are a great refresher of concepts. I can't wait to be back when I prep for my DAT. Thank you!

[@ChadsPrep]

Glad you are here - Happy Studying!

[@robertluca6835]

Your circle method for determining stereochemistry is LIFE CHANGING. THANK YOU

[@ChadsPrep]

Glad you think so, Robert - you're welcome!

[@katlegomkay4671]

After all the struggle😅, you simplified this topic in less than an hour. Thank you🙏

[@ChadsPrep]

Glad to hear - Happy Studying!

[@laylaeddinson6992]

Thank you so much for taking the time in making these helpful videos. You really make ochem less daunting. I'm looking forward for the next few video lessons on this topic.

[@ChadsPrep]

Glad you find the videos helpful, Layla - hope you keep enjoying them!

[@noraasker9425]

Thank you so much for the great videos! One of the most in-depth and well-rounded orgo channels on youtube!

[@ChadsPrep]

You're welcome - Thanks for saying so!

[@JasonLeon-baybeeee]

Chad your work is so helpful. You make seemingly complicated concepts simple enough to to understand. Thank you Chad!

[@ChadsPrep]

You're welcome and Thank You for saying so.

[@26d8]

this is a very helpful video, clarified this topic well, literally covered 5 lectures for me. Thank you so much for making this.

[@ChadsPrep]

Glad it was helpful, Samira, and thanks for your comment!

[@ChadsPrep]

And btw Samira. I don't know if you're class is covering the pericyclic reactions in general but the next three lessons which will be released over the next few days will be over cycloaddition reactions, electrocyclic reactions, and sigmatropic rearrangements. Again, glad you found this helpful!

[@26d8]

@@ChadsPrep Hi Chad, yes the next lectures would by on heterocycle reactions and the topic you just mentioned are already covered too, I'm waiting for your new releases. Really appreciate your time and videos. 👌🏻👌🏻👌🏻😊

[@kagamer21]

Thank you, Chad!!!

[@ChadsPrep]

Most welcome, Nicholas!

[@jackbursal7208]

Around 36:47 wouldn't you rotate the dienophile to have the carbonyl groups on the LHS for the endo rule? I'm just a bit confused. But overall great video.

[@keroloshanna3750]

Really appreciate you ❤

[@ChadsPrep]

And we appreciate you :)

[@sciencenerd7639]

you are fantastic! thank you

You're welcome and Thank You!

[@denissemedina4619]

I have a question, how do you know when to flip the dienophile? or it has to do with the resonance?

[@ChadsPrep]

I believe you're referring to the regioselectivity of the reaction which is related to some resonance considerations and is covered beginning about 19:00. But ultimately, you are trying to avoid 1,3 relationships between an electron-donating group on the diene and an electron-withdrawing group on the dienophile. We often 'flip' the dienophile to avoid these 1,3 relationships. Hope this helps!

[@maryo5278]
