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

`CH_(3)COCH_(3)`

`(CH_(3))_(2)CHOH`

`CH_(3)CHO`

`CH_(3)CH_(2)OH`.

Text Solution

Verified by Experts

The correct Answer is:

Since the product reacts with phenyl hydrazine , it must be an aldehyde or a ketone . But it does not answer silver mirror test , therefore , it cannot be an aldehyde , hence it must be a ketone.
