The compound that does not undergo haloform reaction is

A) $CH_{3}CHO$

B) $CH_{3}CH_{2}OH$

C) $CH_{3}COCH_{3}$

D) $C_{2}H_{5}COCH_{2}CH_{3}$

Option D

The Haloform reaction is given by aldehydes and ketones containing three $\alpha$-H atoms and alcohols containing

group

In other words all the methyl ketones

and only acetaldehyde (ethanal)

($CH_{3}CHO)$ can give this test

$CH_{3}CH_{2}OH$ $ \underrightarrow{NaOH+I_{2}}$ $CH_{}I_{3}+HCOO^{-}$

$C_{2}H_{5}COCH_{2}CH_{3}$ $ \underrightarrow{NaOH+I_{2}}$ does not give Haloform test.
