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_(3)COCH_(3)`
B. `(CH_(3))_(2)CHOH`
C. `CH_(3)CHO`
D. `CH_(3)CH_(2)OH`

Answer

B

Explanation

The oxidation product of X reacts with phenyl hydrazine, thus it contains
`gt C=0` 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))_(2)CHOH`.
