Vedclass · Answer

(D) The reaction of a Grignard reagent $(CH_{3}MgBr)$ with epoxides followed by hydrolysis $(H_{2}O)$ yields alcohols.$1$. Reaction with ethylene oxide $(C_{2}H_{4}O)$ gives a $1^{\circ}$ alcohol: $CH_{3}MgBr + C_{2}H_{4}O \rightarrow CH_{3}CH_{2}CH_{2}OH$ (Propan$-1-$ol).$2$. Reaction with propylene oxide $(CH_{3}-CH-CH_{2}-O)$ involves the nucleophilic attack of $CH_{3}^{-}$ at the less hindered carbon atom,resulting in a $2^{\circ}$ alcohol: $CH_{3}MgBr + CH_{3}-CH-CH_{2}-O \rightarrow CH_{3}-CH(OH)-CH_{2}-CH_{3}$ (Butan$-2-$ol).$3$. Reaction with acetone $(CH_{3}COCH_{3})$ gives a $3^{\circ}$ alcohol: $CH_{3}MgBr + CH_{3}COCH_{3} \rightarrow (CH_{3})_{3}COH$ ($2$-Methylpropan$-2-$ol).Therefore,propylene oxide gives a $2^{\circ}$ alcohol.

Which of the following gives a $2^{\circ}$ alcohol as a major product upon reaction with $CH_{3}MgBr$ followed by $H_{2}O$?
