Vedclass · Answer

(B) The formation of a pair of enantiomers (a racemic mixture) occurs in $S_N1$ reactions where a planar carbocation intermediate is formed. In the reaction of $2$-iodo-$3$-methylbutane with $H_2O$,the mechanism proceeds via the $S_N1$ pathway. The leaving group $(I^-)$ departs to form a carbocation,which is planar. The nucleophile $(H_2O)$ can then attack from either side of the planar carbocation,leading to the formation of both enantiomers in equal amounts,resulting in a racemic mixture ($dl$ mixture).

Which reaction results in the formation of a pair of enantiomers?
