Description: Advanced treatment of basic mechanistic principles of modern organic chemistry. Topics include molecular orbital theory, orbital symmetry control of organic reactions, aromaticity, carbonium ion chemistry, free radical chemistry, the chemistry of carbenes and carbanions, photochemistry, electrophilic substitutions, aromatic chemistry.

This video is part of a 20-lecture graduate-level course titled "Organic Reaction Mechanisms I" taught at UC Irvine by Professor David Van Vranken.

Recorded October 5, 2012.

As a chemistry professor I can say that these lessons are SO valuable to learn. I wish that we had more time to teach them in a normal organic chemistry sequence. UCI students are really lucky to be able to take a class dedicated entirely to these topics.

Can’t believe this is ten years old. Absolutely timeless and masterful exposition of frontier molecular orbital theory!

[faizan]

No wonder Americans are so much better at research, when you have teachers like that

I really liked how he pointed out that log-based calculations are not intuitive.

Energy difference is in the denominator, not the numerator.

Great prof love your lectures

[Carlisle]

Brilliant! Thank you for making these lectures accessible to anyone!

Beautiful lecture. But cameraman should not move the camera so much. SO painful to eyes.

[Duarte]

Awesome lecture, but I just can't concentrate with this camera movie every second. :(

[popwavy]

Thank you really dr. :)
I have a question ... why ( pi orbitals ) have lower energy than ( n ) although ( n ) is hybrid containing s character ! while pi orbitals formed of pure p orbitals

[faheemarahman]

Amazing professor, totally seeing organic chem in a different light. Please can you explain 23.56 how does long bond length make alkyl halide more nuecleophilic? does not it make it more electrophilic as it is easier to accept electrons to the anti bonding C-I.

[peijunli]

nice lecture, but the camera moving makes me sick

[azuraijin]

Isn't the ([B]/[A]) : deltaG relationship of [B]/[A] = 10^(deltaG/-1.4 kcal/mol) or [B]/[A] = 10^(deltaG/-5.9 kJ/mol) not only valid if you assume a temperature of T = 310 K? And is that a reasonable assumption, when many in vitro organic reactions are not performed at 37 °C?

[madansharma]

Can one explain the MO energy difference to explain crazy reactivity of Iodide ion.

[kawsar]

Good Undergraduate Chemistry lecture 😢😮😅

[nilsnickname]

but video quality while camera is moving is very very bad

[JohnDoe-nlsf]

Sorry but the way the camera is moving all you can get out of it is motion sickness.

[govindpratapsingh]

Which book is good for this topic, any input please
