Vedclass · Answer

(A) In acetamide $(CH_{3}CONH_{2})$,the nitrogen atom has a lone pair that participates in resonance with the $C=O$ group. However,the $-NH_{2}$ group is a stronger electron-donating group by resonance compared to the $-OC_{2}H_{5}$ group in ethyl acetoacetate $(CH_{3}COCH_{2}COOC_{2}H_{5})$.Because nitrogen is less electronegative than oxygen,the lone pair on nitrogen is more readily donated into the carbonyl system,increasing the electron density on the oxygen atom of the $C=O$ bond,which makes the $C=O$ bond more polar.Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation for the Assertion.

Assertion: Acetamide has a more polar $C=O$ group than ethyl acetoacetate.
Reason: $-\ddot{N}H_{2}$ is more electron-donating than $-\ddot{O}C_{2}H_{5}$.
