An organic compound "X" having molecular formula `C_(5)H_(10)O` yields phenyl hydrazone and gives negative response to the lodoform test and Tollen's test. It produces n-pentant on reduction. 'X' could be:

A

3-pentanone

B

n-amyl alcohol

C

pentanal

D

2-pentanone

Text Solution

Verified by Experts

The correct Answer is:
A
Since the compound forms a phenylhydrazone, it is a carbonyl compound (contains aldehydic or ketonic group) Since it does not respond to Tollen's reagent test it, is not an aldehyde. Moreover, it does not contain a methyketonic group `(-overset(O)overset(||)(C)-CH_(3))` as it does not give iodoform test. This means that the given compound is `3`-pentanone or pentan-3-one.
