"WebE2: favored by a strong base. SN2: favored by a good nucleophile (relatively weaker base) SN1/E1: It is hard to separate SN1 and E1 completely because they both go through carbocation intermediates and are favored by a poor nucleophile/weak base, for example, H 2 O or ROH (solvolysis). Under such neutral conditions, S N 1 and E1 usually occur ... " - E1 versus sn1 reactions

WebThe factors that will decide SN1 vs SN2 and whether it is SN1, SN2, E1, E2: 1) Do you have a strong nucleophile? If you do, it will favor an S N 2 reaction in the S N 1 vs S N 2 fight. … WebNo, 2° substrates can react via SN1 or SN2, depending on the conditions. We have two competing processes. If the nucleophile attacks faster than the leaving group spontaneously leaves, the reaction is SN2. If the leaving group leaves before the nucleophile can successfully attack, we have SN1.
