We can promote S_N2 over S_N1 reactions if we:
I.use a substrate that gives a primary carbocation and not tertiary carbocation
II.use a sterically hindered substrate
III.use a polar protic solvent

Quizplus · Accepted Answer

Using a substrate that gives a primary carbocation favors S_N2 reactions because primary carbocations are less stable and do not favor S_N1 reactions, which involve carbocation intermediates.
