Sn1 reactions have the fastest rate when the substrate can from a relatively stable carbocation. The factors affecting the rate of s n 2 reactions are, therefore, important to understand in order to achieve the product in minimum possible time.

This Means That It Will Not Take Very Much Strength.

Factors affecting the s n 2 reaction as we saw in the previous section, in the s n 2 reaction the rate of reaction depends on both the electrophile (usually an alkyl halide) and the nucleophile. Rate of sn2 reaction due to concentration and strength of nucleophile. The s n 1 reaction is a substitution nucleophilic unimolecular reaction.
