1.Benzaldehyde reacts with acetic anhydride, (CH3CO)2O(\text{CH}_3\text{CO})_2\text{O}(CH3CO)2O, in the sequence: (i) CH3COONa\text{CH}_3\text{COONa}CH3COONa (A), then HBr→\text{HBr} \rightarrowHBr→ (B); (ii) hydrolysis. The product B is:a.Ph-CHBr-CH2-COOH\text{Ph-CHBr-CH}_2\text{-COOH}Ph-CHBr-CH2-COOHb.Ph-CH=CH-CH2Br\text{Ph-CH=CH-CH}_2\text{Br}Ph-CH=CH-CH2Brc.Ph-CH2CH(Br)COOH\text{Ph-CH}_2\text{CH(Br)COOH}Ph-CH2CH(Br)COOHd.Ph-CH=CH-COBr\text{Ph-CH=CH-COBr}Ph-CH=CH-COBrLogin to continueOnly logged in users canattempt or see the solution.
