$Ph-C(=O)-CO_2H$

Vedclass · Answer

(B) The reaction of acetophenone $(PhCOCH_3)$ with $NaNO_2/HCl$ leads to the formation of an isonitroso compound (oxime),$PhCOCH=NOH$ (Product $A$).Treatment of the oxime with acetic anhydride $(Ac_2O)$ followed by heating causes dehydration to form the nitrile,$PhCOCN$ (Product $B$).Finally,the acid-catalyzed hydrolysis of the nitrile group $(CN)$ yields the carboxylic acid group $(COOH)$,resulting in the final product $PhCOCO_2H$ (Product $C$).

$Ph-C(=O)-CH_3$ $\xrightarrow[HCl]{NaNO_2} (A)$ $\xrightarrow[heat]{Ac_2O} (B)$ $\xrightarrow{H_3O^{+}} (C)$
Product $(C)$ of the above reaction is
