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?
@jjsearson I don't think you're supposed to do that because autoionization to H3O+ and OH- happens only to a small extent, so it wouldn't be a feasible reaction.
you seriously saved my butt in my college Ochem class! Can't thank you enough for taking the time to not only make these videos but also making them available to everyone! Thank You Thank You Thank You!!
@rahishg I am an organic chem student and by no means an expert! However I think this is one area I am comfortable in. In order to know where any stereo center is located you must check to see if the carbon in question is sp3 hybridized and has 4 different groups attached to it. In this case, if we know the reaction is going to be an Sn1 then we know there is going to be a retention in stereochemistry ( configurations will stay the same), that is if there is any stereocenters involved.
@rahishg If we look at tert-butyl iodide (what we started with) it is sp3 hybridized but has 4 methyl groups attached which would rule out the possibility for a stereocenter. Hope that helped...
I love chemistry but i was reconsidering doing it because the lectureres at my uni make no sense! but you ignited my love for chemistry again :D THANK YOU SO MUCH and may god bless you.
man if only i found these vids 2 years ago when i barley got through ochem maybe ill retake ochem 1 and 2 now lol.Oh and he def got me a great MCAT score i will be donating to you man give me a few years lol i will ever forget.
Bad news about your donation program: college students are too broke to donate anything.
Good news about donation program: you will be the reason for these college students becoming successful chemists, and they will remember their debt to you
For the past two weeks ive struggled to understand Sn1 and Sn2 reactions. Ive read and reread the chapters in my book, used the online study guide that comes with my book, and used to internet to try to find help understanding this stuff! I am so glad that I found your videos because I finally understand it!!! Thanks a bunch and I wish I would of found these videos earlier!
I love you. You're so cute and the absolute best!!!!!! I lost hope for orgo.. but through watching these, I'm slowly getting there.. :) thanks so much!!! I'll pay when I can!!
i'm so relieved to see people working through the reactions! lecturers tend to just skip through from reagents to product, name the facts n wait for it to click, this really just re affirms my knowledge. thanks heaps
Oh how i wish you were my professor, my teacher only goes through powerpoints which he gets out of the book and just refers to that when you have a question
you are a ridiculously good professor! My prof just zipped through everything like it was nothing... and none of the students got anything. Thanks so much for posting this video!
I watched your videos when I was taking Organic chemistry and it helped me ace the class. Now Im studying for my DAT, I am back to watch your videos. You have been a great help !!!!
THAAAAANKS... omg its 1 am here in TX... i cant stop watching these vids, because now i like SN2, SN1, E1, E2 because i finally get it. my light bulb turned back on. thank you :)

Could you have skipped the ----H20+ intermediate, and just used OH- as the nucleophile? (considering that water auto-ionises)

How was it known the first reaction was SN1 and not an SN2 reaction?
kingbiscuit28 9 months ago
@kingbiscuit28 The reaction happens on a tertiary carbon. It's too hindered to be SN2
