Reacts with Tollen's reagent to form silver mirror

Vedclass · Answer

(B) Acetophenone is a ketone $(C_6H_5COCH_3)$.$1$. Ketones do not react with Tollen's reagent,so they do not form a silver mirror.$2$. Acetophenone contains a methyl ketone group $(-COCH_3)$,so it gives a positive iodoform test with $I_2/NaOH$.$3$. It reacts with $2,4$-dinitrophenylhydrazine to form a hydrazone derivative.$4$. Oxidation of acetophenone with alkaline $KMnO_4$ followed by hydrolysis yields benzoic acid.Therefore,the statement that it reacts with Tollen's reagent to form a silver mirror is false.
