An organic compound \(A\) is oxidised by using acidified \(K_2Cr_2O_7\) solution and form compound \(B\), compound \(B\) gives \(DNP\) test but not silver mirror test, then compound \(A\) is
1 \(2-\) propanol
2 \(1\) -propanol
3 ethanal
4 ethanol
Explanation:
As the compound does not give silver mirror test, it cannot be an aldehyde, Also it reacts with phenylhydrazine therefore, it has to be a ketone which is obtained only when the compound \(X\) is \(2 -\) propanol.
