SN1 and SN2

Postby Alex Nguyen 3I » Fri Feb 26, 2016 10:28 pm

Do SN2 reactions always imply 1 transition state, and do SN1 reactions always imply 2 transition states? Also, what would the transition states be for the SN1 reaction between HO- and CH3Br? I think one of the transition states is going to be CH3 with the Br broken off. What would the second transition state be?

Yes both of your ideas are right. When the Br leaves, what is the charge on C? How do you think that would interact with OH-?

The 1 and 2 in SN1 and SN2 refer to the molecularity, right? Like SN2 = bimolecular. But what exactly does bimolecular mean? Does it have to do with there being 2 different reactants or 2 moles of reactants?
