$CH_3-CN \xrightarrow[\Delta]{H_2O/H^{+}} CH_3-CONH_2$

(D) The reaction of nitriles $(CH_3-CN)$ with dilute acid $(H_2O/H^{+})$ and heat $(\Delta)$ results in complete hydrolysis to form carboxylic acids $(CH_3-COOH)$ and ammonium ions $(NH_4^+)$. The formation of an amide $(CH_3-CONH_2)$ is an intermediate step and is not the final product under these conditions. Therefore,the reaction is incorrectly written.
