SN2 in a polar, protic solvent...why?
« on: November 12, 2010, 06:41:58 PM »


It tells me it should be an SN2 reaction. Why? I thought SN2 reactions had to be carried out in a polar, aprotic solvent or else the solvent would severely retard the reaction by forming a solvent shell around the nucleophile.

edit: Or am I misreading that? "In the presence of NaOH" means NaOH acts as the solvent, correct?

Nevermind, I figured it out. CH3-SH reacts with NaOH to form CH3SNa+ and H2O. CH3SNa+ is then substituted on the cycloalkane.

It means water is the solvent.
