Vedclass · Answer

(D) Compounds containing a carbonyl group at the $\beta$-position relative to the carboxylic acid group ($\beta$-keto acids,$\beta$-imino acids,or malonic acid derivatives) undergo decarboxylation easily on heating via a six-membered cyclic transition state.$A$. $CH_2(COOH)_2$ (Malonic acid) is a $\beta$-dicarboxylic acid and undergoes decarboxylation to form acetic acid.$B$. $Ph-CO-CH_2-COOH$ is a $\beta$-keto acid and undergoes decarboxylation.$C$. $CH_3-C(=NH)-CH_2-COOH$ is a $\beta$-imino acid and undergoes decarboxylation.$D$. $HOOC-CH_2-CH_2-COOH$ (Succinic acid) is a $1,4$-dicarboxylic acid ($\gamma$-dicarboxylic acid). Upon heating,it undergoes dehydration to form succinic anhydride rather than decarboxylation.
