Is Sn1 Reaction Stereospecific?

SN1 reactions are nucleophilic substitutions, involving a nucleophile replacing a leaving group

leaving group
The physical manifestation of leaving group ability is the rate at which a reaction takes place. Good leaving groups give fast reactions. By transition state theory, this implies that reactions involving good leaving groups have low activation barriers leading to relatively stable transition states.

(just like SN2). However: SN1 reactions are unimolecular: the rate of this reaction depends only on the concentration of one reactant.

Is SN1 reaction stereoselective?

Complete step-by-step answer:

For SN1 reaction, the SN1 reaction proceeds through two steps. In the first step the carbocation is formed from the removal of the leaving group. ... The rate of the reaction depends upon the carbocation. The reaction is non-stereospecific as (attack by nucleophile can occur from both sides).

Are SN1 and SN2 reactions stereospecific?

The SN2 reaction is stereospecific. A stereospecific reaction is one in which different stereoisomers react to give different stereoisomers of the product. For example, if the substrate is an R enantiomer, a frontside nucleophilic attack results in retention of configuration, and the formation of the R enantiomer.
