Vedclass · Answer

(B) The reaction involves the treatment of $2$-hydroxy$-2-$cyclohexylacetic acid with $3$ equivalents of $EtLi$. First,$2$ equivalents of $EtLi$ act as a base,deprotonating both the carboxylic acid group and the hydroxyl group to form a dianion. The third equivalent of $EtLi$ then acts as a nucleophile,attacking the carboxylate carbon. Upon acidic workup $(H_3O^+)$,the intermediate forms a gem-diol,which is unstable and loses water to form a ketone. The final product is $1$-cyclohexyl$-2-$hydroxybutan$-1-$one,which corresponds to the structure in option $B$.
