S_(N)1 reactions are accompanied by racemization in optically active h – InterviewSolution

1.	S_(N)1 reactions are accompanied by racemization in optically active halides.
Answer» SOLUTION :In `S_(N)1` reactions, carbocations are the INTERMEDIATES. Since carbocations are planar species, therefore, attack of the nucleophile on them cann occur from both the sides (front and rear) with ALMOST equal ease GIVING a 50:50 mixture of the TWO enantiomers, i.e., a racemix mixture is obtained.
