Question about SN2

(1/3) > >>

LuckyDude35:
Got a couple of questions, I have a question that is: bromomethane + hydrogen sulfide in DMF (at 25 degrees C). I know the S acts the nucleophile and the Br is the leaving group. My question is what happens to the hydrogen that was on the S? Does it bond to the Br now? Thanks for your *delete me*

movies:
Yeah, you get HBr as a side product.  It will be dissociated into H+ and Br- ions, most likely.  In these reactions there is typically some kind of non-reactive base to absorb the acid that is produced.

LuckyDude35:
alrighty, then I have another question. I am trying to work on 1-methylcyclopentanol + HCL (at 0 degrees C), Im not sure where to start with this one, any help?

movies:
Well, give me your thoughts on it.

LuckyDude35:
The  0 degrees seems odd to me. I would think that the Cl from the HCL would be the nucleophile, would the OH come off of the 1-methylcyclopentanol? Would this be SN2 then?
