Ok I just need a QUICK response - Sn1 vs Sn2 chemistry
« on: October 31, 2012, 10:51:01 AM »
Can someone please tell me the answer to this?

Predict the product for the reaction of R-2-chlorobutane with NaI in acetone, indicating CORRECT stereochemistry.

I entered "S-2-idobutane" but it marked it as wrong.
What's the answer?

Well if it an SN2 reaction and it is then they proceed normally with inversion of stereochemistry. So your answer is correct unless I am missing something.

Is it possible that you did not choose "iodobutane," as opposed to "idobutane?" In other words, did you spell it correctly?  If this is a multiple choice format, then it would obviously be impossible to spell incorrectly

Oh oops I mispelt it here...
But yes I did put " (S)-2-iodobutane " and it said I was wrong (?)
And this is a fill in the blank problem on Webassign. :(
Either webassign is wrong or this is impossible.

Maybe I just have to enter "(S)-2-iodobutane" (like S-2-iodobutane) without the parenthesis since the molecule in the question doesn't have the parenthesis (?)

Oh wait I got it right! :D
Thanks everyone!
The answer was supposed to written: S-2-iodobutane
