Question

Write the Sn2 mechanism for the reaction that you have performed?

Answer 1

Nu: + R3C-Lv → Nu--R3C--Lv → NuCR3 + Lv:,

Where Nu: is the nucleophile, Lv is the leaving group, R can be either alkyl or H (but works best with two H's), and the middle species being the transition state in which the nucleophile and leaving group are partially bonded to the carbon, which flips the R conformations in the final product. This is true of any Sn2 reaction, although it is possible for Nu: and Lv: to be either neutral on negatively charged. If the leaving group is hydroxyl, there has to be an acidic proton source in order for the leaving group to be a water molecule.
