The substitution reaction of optically active alkyl halides in which attack of nucleophile and detachment of halogen takes place in two different steps and racemic mixture is formed as product is:
SN1 nucleophilic substitution reaction
The substitution reaction of optically active alkyl halides in which attack of nucleophile and detachment of halogen takes place in two different steps and racemic mixture is formed as product is: SN1 nucleophilic substitution reaction.
In this mechanism first the removal of halide ion takes place and a carbocation is formed. A carbocation has a planar geometry.
