Q. A compound $ C_{5}H_{10}O (A) $ forms a phenyl - hydrazone and gives negative Tollen's test and a positive Iodoform reaction. It also gives $ n $ -pentane on reduction. The compound $ (A) $ is

AMUAMU 2018Aldehydes Ketones and Carboxylic Acids

Solution:

Since, the compound $(A)$ gives a positive iodoform test but negative Tollen's test, so it must be a methyl ketone. From the given molecular formula $C_{5}H_{10}O(A)$ can be $2$-pentanone
