SN reactions entail several steps. It begins with the removal of the leaving group, which results in carbocation and attack by a nucleophile. The SN1 and SN2 have very little difference from each other. SN1 is non-stereo specific and depends on the substrate, while SN2 depends on a nucleophile and substrate. SN2 occurs in a non-polar solvent. SN1 reactions require several steps, while SN2 reactions only have one level.

SN1 response has a first-order dependence on nucleophiles. A carbocation is established as an immediate reaction, and this type of response typically happens in the secondary and tertiary alcohols. In SN 2 reactions, one bond is broken, and another bond is formed concurrently. This bond means the displacement of the leaving group by a nucleophile.
