Vedclass · Answer

(A) $1$. The $DNP$ test ($2$,$4$-dinitrophenylhydrazine test) is given by aldehydes and ketones.$2$. The silver mirror test (Tollens' test) is given by aldehydes but not by ketones.$3$. Since compound $B$ gives the $DNP$ test but not the silver mirror test,$B$ must be a ketone.$4$. $A$ secondary alcohol is oxidized by acidified $K_2Cr_2O_7$ to form a ketone.$5$. Among the given options,$2-$propanol is a secondary alcohol,which on oxidation yields acetone (propanone),a ketone.

An organic compound $A$ is oxidized using acidified $K_2Cr_2O_7$ solution to form compound $B$. Compound $B$ gives the $DNP$ test but not the silver mirror test. Then,compound $A$ is:
