Vedclass · Answer

(C) The reaction involves the alkylation of cyclohexanone using excess $CH_3I$ and $KH$. $KH$ is a strong base that deprotonates the $\alpha$-carbons of the ketone to form enolate ions. Since $KH$ and $CH_3I$ are in excess,all four $\alpha$-hydrogens of the cyclohexanone are replaced by methyl groups. First,the two $\alpha$-carbons are deprotonated to form a dienolate,which then reacts with $CH_3I$ to form $2,6-$dimethylcyclohexanone. Further treatment with excess $KH$ and $CH_3I$ leads to the substitution of the remaining two $\alpha$-hydrogens,resulting in $2,2,6,6-$tetramethylcyclohexanone.
