Solution

The correct option is B $3 > 4 > 2 > 1$
Given
Solution :
Alkyl groups and alokxy groups add electron density to carbonyl carbon.
Because of their low reactivity, amide do not participate in nearly as many nucleophilic substitution reactions
The decreasing order of electrophilic character of carbonyl carbon is
$a l d e h y d e > k e t o n e > e s t e r > A m i d e$
Hence, the decreasing order of reactivity for the nucleophilic addition reaction is
$a l d e h y d e > k e t o n e > e s t e r > a m i d e$
The correct option is option B. 3>4>2>1
