Vedclass · Answer

(A) The silver mirror test (Tollens' test) is given by aldehydes and $\alpha$-hydroxy ketones. Among the given compounds:$1$. Formic acid $(HCOOH)$ contains an aldehydic hydrogen atom attached to the carbonyl group,which allows it to be oxidized to $CO_2$ and $H_2O$ by Tollens' reagent,thus giving a positive silver mirror test.$2$. Formaldehyde $(HCHO)$ is an aldehyde and gives a positive silver mirror test.$3$. Benzaldehyde $(C_6H_5CHO)$ is an aromatic aldehyde and gives a positive silver mirror test.$4$. Acetone $(CH_3COCH_3)$ is a ketone and does not give a silver mirror test.Therefore,compounds $A$,$B$,and $C$ will give a silver mirror test.

$(A)$ Formic acid
$(B)$ Formaldehyde
$(C)$ Benzaldehyde
$(D)$ Acetone
