Pastor Gains it's okay because you're triene your best

[@usmanchughtai1751]

Thank you! I learned more about this topic in 8 minutes than I did in a week of lecture. Seriously, you rock!

[@shivanisaluja4757]

I am thankful to you from the bottom of my heart. I have an exam tomorrow and couldn't ask for any better explanation than this✨

[@kristianlaursen2733]

if only my teacher gave diels alder questions as simple as these...

[@drbeti6225]

Honestly, I'm thankful with the core of my heart. Our teacher had named this cyclohexene product as "tetrahydro benzaldehyde" -.- . But now I'm clear in it's concept. God bless you!

[@ambermichalk3373]

within 2.5 min i had a revelation and understood everything!! GREAT EXPLAINATION

[@dosvedania]

Extremely helpful, when you explained it, it looks like the easiest reaction in the world (on paper). I really have to question myself as to why I don't understand it when my professor teaches it. I'm thinking it is because I am actually paying attention and I looked up this video on my own time while I have to get to class by a certain time. x) Thanks for the help!

[@schrodingercut1837]

One of complicated mechanism, that I was trying to figure out was here in such a easy way ...thanks a lot❤️

[@rachel_dittrich]

This was a great explanation!! I’ve spent the past week and a half trying to understand this reaction. Thank you so much for your help!

[@tarawelch9527]

You make my life so much easier and sometimes you make me stop crying. Lol. Thank you!

[@hannahmuskal3884]

The mechanism makes SO much sense with this video thank you!!

[@marcamilaar]

I wish you were my professor

[@MrAnnoyingalperen]

Professors that are over 90 seriously shouldn't teach. The guy spent 30 mins on this topic trying to stay alive instead of fkn keeping it simple. These videos are amazing.

[@kyleboonyong5930]

2:15 Technically speaking, I believe it does matter what directions the pi bond electrons are moving/being pushed? Since there is an electron withdrawing group (EWG), it takes away electrons from the alpha carbon. Thus it is partial positive there/electrophillic character. Since at that spot its electrophillic character, it would prompt for an nucleophillic attack by the pi bonds. Thus electron pushing is created in the clockwise fashion. Let me know what you guys think. Yes, I understand it creates the same product. But from a formal standpoint, does my logic make sense?

[@kyleboonyong5930]

Sorry wrong time. Look at 1:58 to understand what I am talking about

[@Andytk33]

I completely agree. It's been a year since I've done any organic chemistry and just getting back to it for fun and noticed that too. You have the correct reasoning here. It might not be important if you're just wanting to remember the Rx but it's important if you have a larger molecule and want to know what reacts first, when and where. So yeah, very important actually! Haha :) what are you up to nowadays? It's been 2 years since your post. Are you working in chem or still at school now?

[@tiagoneymar9823]

wow thank u the colored bonds helped me to understand it very clearly

[@chaudharyharris6008]

Please make videos on Electrocylic and Sigmatropic Pericyclic reactions

[@danabaldisimo1473]

thank you, thank you and a thousand more

[@dannyawesome63]

THANKS SO MUCH! THIS REALLY HELPED!!

[@mattomatt20]

Sal you are an amazing teacher thank u!

[@opus-7L]

Best explanation ever, I even subscribed because of it. Thank you so much

[@benchkings]

U my friend r a savior

[@lilac749]

This was very helpful!!

[@jezioratm]

Thanks a lot ! It was awesome :D

[@mohamedayman144]

Very helpful...Thank u

[@sweetcorina12]

Great explanation. Thank you.

[@utkarshsaxena2362]

if we will get videos which would help us in our post graduates chemistry courses and net topics in chemistry in detail that will be very good and will be very good for the students seeking higher education in chemistry. #khan academy

[@Sjj8d]

Thanks😊

[@JUNEDKHAN-jf5ld]

Thank you so much sir for this wonderful presentation it is very helpful.

[@mahimissra2000]

Thanks it was really helpful :)

[@jakobdavis732]

Any one else prefer studying with videos? Kind of obsessed with Numerade for their lesosn videos lately...

[@evangood9697]

Excellent video!

[@iamsaiankit]

Had a test yesterday and your video saved me ! i got an A grade !!! i thank you so much!!!!!!!!!!!!!!!!!!!

[@honeypot2483]

thank you!!!

[@sahert494]

really helpful thanks! :)

[@melyna-5568]

Thank you

[@RoseRose-gw2ot]

great work

[@johnmandrake8829]

you da champ

[@Sarmad.S]

OC SQUAD PUT UR HANDS UPPP ✋

[@jacoballiston7574]

I want Sal to be teaching me this 😢

[@DallinVaughn]

I thought you couldn't rotate about a double bond? at 3:57

[@josphellihsilak4588]

Carbons 2 and 3 arent double bound, they can rotate. The bond between 1 and 2 and 3 and 4 are pi bonds, they cant rotate.

[@toobaahmad2658]

Omo. Omo. Well done!

[@krishnapokharel2581]

LUMO of ethylene and HOMO of 1,3 butadiene are antarafacial but HOMO of ethylene and LUMO of 1,3 butadiene are suprafacial, how?

[@agdoombagdoom8540]

Dankeshön

[@muneeralam4478]

giving 1 like above and 1000 likes in comment... (perfect)

[@geugeumuginastiti5890]

this is helpful!!!!

[@lopyus]

what about the EWGs and EDGs do they have any effect?

[@mrobjectoriented]

Ashish Barnawal He mentioned the role of EWG to make dienophiles election deficient.

[@karimrifai7660]

You're a fuckin god

[@mickelliu5559]

I am ready to donate
