  • based on your table, the only case wehre E1 reaction can take place is with a 2* or 3* alpha-carbon with a poor Nu/weak base or 3* alpha-carbon with a good nu/weak base. But you state here that because the majority of the reaction (95%) is Sn1 you leave out the E1. So in what case would one want to only do the E1 reaction or have an E1 reaction majority?

  • you should protonate the I first to make it a better leaving group then attack with the OH-

  • this friggin black board man.. i always think that white brick on the board is a negative charge

  • 0 ppl disliked this....

  • Question: What exactly causes the leaving group to want to leave the alpha carbon in the SN1 reaction? In one of the earlier videos you were able to clarify why the ions leave one another in an ionic bond (nature doesn't favor charges) but isn't the Iodine "happy" covalently bonded to the alpha carbon? Thanks!

  • he reminds me of jacob two two ...lol..but great job. great job!

  • i love you

    

  • what table is he referring too?

  • @206BESTOFTHEWEST It's on his website.

  • Great prof. Excellent teaching skill. I wish all the professors are like you. I hope you have changed so many people's life. Thank you.

  • You are just too helpful - you are so good at summing things up in two sentences unlike my textbook which takes 2 pages to explain the same thing. thankyou

  • You are a wonderful teacher! Thank you for allowing us access to your videos.

  • who is the student in this video lol?

  • Can you put upload the handout you talk about in the videos online so we can use it as well?

    Thank You So much for the video! You are a life saver!

  • this lecturer is really cool ,he has helped me lots especially with nmr spectrum ,those guys he teaches are luck ,cos hes good at explaining.

  • This is so helpful. I've been in Organic Chemistry for 3 months and you make me feel like I'm learning this for the first time. Thank you.

  • can i find that chart anywhere?? it sounds very helpful..

  • @xxSUSHixx he has it on his website.

  • I have a question about the problem at the begining (0:00 to 0:48): what about carbocation rearrangement of where Iodine left? (wouldn't that carbocation rearrange from primary to secondary because it's more stable?)

    Professor, could you please answer that question for me? or anyone who knows it well?

  • These videos are great. They are helping me out quite a bit. Thank you!

  • thanks alot sir for your videos, helps out so much since you give alot of examples.

    God bless

  • Thank you very much, these videos are great! One thing tho - there is no such thing as a "stereocenter", stereogenic center is more correct (a center cannot have stereochemistry although a molecule can). :-)

  • actually my orgo professors (I go to Cornell) call them stereocenters also. so... yea.

  • Figures I'd run into a fellow Cornellian on here, good luck on the prelim in a few days :)

  • hahaha thanks. you too. PS this guy totally saved me because I learn nothing from jon. good luck!!

  • Yeah I'm not here to preach, a lot of really competent professors call them stereocenters, but if you consider the meaning of the words you realize that a center cannot in any way be "stereo", only in it's surrondings - hence the name stereogenic center.

  • @erlover3

    Well just because a professor says it doesn't mean it's right my friend. Swallow your big american pride and accept facts.

  • I basically teach myself using these vids. Great helps!! Thanks for the effort!

  • nice helped me alot. thanks for posting these videos
