Question

what is racemic mixture? why sn1 reaction causes racemization​

Answer 1

Answer:

The carbocation and its substituents are all in the same plane (Figure 1), meaning that the nucleophile can attack from either side. As a result, both enantiomers are formed in an the SN1 reaction, leading to a racemic mixture of both enantiomers. ... The single most important factor is the stability of the carbocation.
