Vedclass · Answer

(C) The reaction of a lactone (cyclic ester) with an excess of Grignard reagent $(CH_3MgBr)$ followed by acid hydrolysis results in a diol. The Grignard reagent attacks the carbonyl carbon twice: the first attack opens the ring to form a keto-alkoxide,and the second attack on the ketone group forms a di-alkoxide. Upon hydrolysis,the product is a diol where one end is a primary alcohol and the other is a tertiary alcohol. Reaction: $\delta	ext{-valerolactone} + 2CH_3MgBr \xrightarrow{H_3O^{+}} HO-CH_2-CH_2-CH_2-CH_2-C(OH)(CH_3)_2$.
