उत्तर
Racemisation occurs in SN1 reaction.
Explanation:
A mixture containing two enantiomers in equal quantities will have zero optical rotation because the rotation caused by one isomer will be neutralised by the rotation caused by the other isomer. This type of mixture is known as a racemic mixture or racemic modification. Racemisation refers to the process of converting an enantiomer into a racemic mixture. Both retented and inverted products are generated during the SN1 reaction. Racemization happens as a result of the production of both d- and l- products.
