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.

Webmore. You have to first consider the fact that in an Sn1 reaction the carbocataion is formed only when the leaving group takes the electron pair and leaves. This happens because of two reasons. 1>The presence of a neucleophile. 2>Stabilization of the negatively charged leaving group by solvation. WebVideo transcript. - [Interviewer] Let's look at elimination versus substitution for a tertiary substrate. For this reaction, we have a tertiary alkyl halide, and we know that a tertiary alkyl halide will form a tertiary carbocation, which is a stable carbocation, and therefore an SN1 reaction is possible. immunotherapy and mrnaWeb4.

Webmore. In a substitution reaction an existing group on the substrate is removed and a new group takes its place. In an elimination reaction the group is simply removed and no new group comes to take its place and this usually results in a double or triple bond forming in the substrate instead. Hope that helps. Comment.

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).
