@@PunmasterSTP not good. I took ochem, physics, calculus, and speech at the same time. I’m sure some people can do that but I’m lazy. Someone convinced me to hurry my curriculum up. I would suggest taking it slow and getting good grades
I can't even tell you how helpful this was! Truly, I don't know why my professor doesn't just watch videos on how to explain the concepts better - this was SO helpful!
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.
Though I'm no longer in ochem and I'm only watching these videos as a review, I feel much the same way about Leah! I know it's been years, but I had come across your comment and became curious. If I might ask, how did your final go?
I would like to personally thank you for helping me out with this difficult part of Alkene reactions! I had a lot of trouble understanding this, previously.
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.
You're so welcome! I'm glad you've found my channel useful! If you're looking for help on your MCAT in the future, I recommend joining my MCAT Study Hall. For more details, visit join.mcatstudyhall.com/ or contact me through my website leah4sci.com/contact/
Such SmoothLy and TechnicaLLy Explained. . . U Just Made this Reaction Mechanism look so Easy. . . THANKZ a Lot. . . Would Love to See Videos on CARBONYL CHEMISTRY Name Reactions from You. . .
I just fell in love with you! I have no background in organic chemistry and this Diels Alder reaction was totally over my head until I found your video! It was so good that now I have to find a way to overcome the secretion of oxytocin in my body!!
As soon as you described this at 7:25 everything clicked!! I've been able to do these cycloadditions but couldn't figure out how to place substituents. Thank you for this!
This was completely insane! I just loved the way you taught thank you so much btw are you having videos on aromatic and anti aromatic compound I really need it ***** mam
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)
Hello Teacher your method is very easy I impress your method please help me in organic chemistry more I wish specialization in organic chemistry you tell me you help me????
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?
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. If you find you need a refresher on Organic functional groups, make sure to read my Functional Groups Guide at leah4sci.com/functional-groups-guide
I am unsure of which part of the video you are referencing in your second question. Since I don't offer tutoring over social media, to get help with questions like this and more, I recommend joining the organic chemistry study hall.

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?
I'm sorry, but I don't offer tutoring over RU-vid comments. For more help with this, I recommend joining the orgo study hall. Full details: leah4sci.com/join
Great question! For more on the stereochemistry of the Diels Alder reaction, watch my newest video in the series first. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Pvu59IJ4vE8.html
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
first of all, she has a lot of knowledge. Obviously. Secondly, what if she learned by some off chance by experimentation? Then her credentials would be the same for those who in earlier years came up with some kind of class or course, taught by some knowledgeable person, (Today's professor) about Chemistry ! One does not have to have some kind of degree in "any" subject to teach it. These are just tutorial courses moron !!
