Vedclass · Answer

(C) $1$. Succinic acid on heating loses a water molecule to form succinic anhydride $(A)$.$2$. Succinic anhydride reacts with $NH_3$ followed by heating to form succinimide $(B)$.$3$. Succinimide undergoes the Hofmann bromamide degradation reaction with $Br_2/KOH$. This reaction converts an amide group into a primary amine with the loss of one carbon atom as $CO_2$. In this case,the ring opens to form $\beta$-alanine derivative,specifically $\beta$-aminopropionate potassium salt,$CH_2(COO^-K^+)-CH_2NH_2$.

Succinic acid $\xrightarrow{\Delta } (A)$ $\xrightarrow[\Delta ]{NH_3} (B)$ $\xrightarrow[KOH]{Br_2} (C);$ Product $(C)$ will be
