JEE Main Chemistry question

Correct order of reactivity of acid derivatives towards a nucleophile is

(A)RCOCl > (RCO)₂O > RCOOR > RCONH₂Correct
(B)RCOOR > RCOCl > RCONH₂ > (RCO)₂O
(C)RCONH₂ > (RCO)₂O > RCOOR > RCOCl
(D)(RCO)₂O > RCOCl > RCOOR > RCONH₂

Answer: (A)

Solution

Nucleophilic acyl substitution reactivity decreases as the attached heteroatom donates more electron density into the carbonyl by resonance (reducing electrophilicity) and
