Organic chemistry: Diels-Alder reaction (5)

Organic chemistry: Diels-Alder reaction. Dienes, dienophiles; s-cis, s-trans; electron-donating and electron-withdrawing substituents; outside vs. inside positions; endo vs. exo approaches. Molecular orbital diagram for Diels-Alder transition state (Frontier Molecular Orbital Theory); molecular orbital diagrams for endo vs. exo transition states.

you are a gift from God. Thanks

[GOOBLE07]

I will donate you money once I start making the big bucks :D

The subtitles are WAY OFF."...army radovan spoons ask that sentencing pulp fiction don't you know sustations is still stick..." That MUST be a troll; not even Google would get it that wrong.

[10jojoan]

you are amazing at explaining. Thank You! :)

[Niravana21]

he def bangs the girls afterwards...whattabro

[babygurll7]

Makes soo much more sense! My professor just went by this soo fast without explaining it and he just wrote it on the board and I copied it. But now with you to go along with my notes, I understand it soo much better and the inside outside thing makes sense!

If only this guy had been a detective on the left hand killer case.

crystal clear!! <3

[c0lleen]

thank you for the inside-outside! i am now enlightened. i am trying to draw them using molecular orbitals but things just get more confusing because i can't imagine substituents rotating on my mind :))

[tbair100]

omg i never knew that the in and out positions only applied to the diene that makes so much more sense! my prof just flew by this material and didn't really explain it. now i can see that this stuff isn't too bad after all. seriously thanks for everything and making these videos available for poor college students. if anyone thinks this guy sucks go get a tutor n spend a good 80 for an hour n a half.

I created a youtube account just so I could comment saying that you are an angel on earth. Wow. Seriously. Wow. I go to a a top 25 school and you are still 10x better at explaining organic chemistry. You are my savior. Expect a large sum of money headed your way.
