An organic compound 'X' is oxidised by using acidified `K_(2)Cr_(2)O_(7)`. The product obtained reacts with phenyl hydrazine but does not answer silver mirror test. The possible structure of 'X' is `:`

Options

A. `CH_3COCH_3`
B. `(CH_3)_2CHOH`
C. `CH_3CHO`
D. `CH_3CH_2OH`

Answer

B

Explanation

The oxidation product of X reacts with phenyl hydrazine, thus it contains `gt` C = O group. The same product does not answer silver mirror test thus, it is a ketone, because only aldehydes give this test.
Thus the compound X must be a `2^@` alcohol, as only secondary alcohols give ketones on oxidation and hence X is `(CH_3)_2CHOH`.
