D

`CH_(3) COCH_(3) gt C_(2) H_(5) COCH_(3) gt CH_(3) `CHO

Text Solution

Verified by Experts

Lesser the number of alkyl groups on the carbonyl carbon, more the reactivity. In general aldehydes are more reactive than ketones for most reactions. Among ketones, larger the alkyl group more the hindrance to external reagents, therefore 2-butanone is the least reactive and acetaldehyde is the most reactive.
