Vedclass · Answer

(B) The reaction involves the ring-opening of an epoxide (or a strained cyclic ether) by a Grignard reagent $(CH_3MgI)$.In the reaction of a Grignard reagent with an unsymmetrical epoxide,the nucleophilic alkyl group $(CH_3^-)$ attacks the less sterically hindered carbon atom of the epoxide ring.Following the attack,the ring opens,and subsequent acidic workup $(H_3O^+)$ protonates the resulting alkoxide to form an alcohol.In this specific case,the $CH_3$ group attacks the less hindered carbon,resulting in the formation of $2$-ethylcyclohexanol.
