Assertion : Acetamide has more polar / C=O group than ethyl aceto… - Vidyadip

MCQ

Assertion : Acetamide has more polar $\begin{matrix}
\backslash \\
/ \\
\end{matrix}C=O$ group than ethyl acetoacetate.

Reason : $\overset{\centerdot \,\,\centerdot }{\mathop{N}}\,{{H}_{2}}$ is more electron donating than $\overset{\centerdot \,\centerdot \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}{\mathop{O{{C}_{2}}{{H}_{5}}}}\,$

✓
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

Answer

Correct option: A.

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

a
$\underset{Acetamide}{\mathop{\begin{matrix}
O \\
|| \\
C{{H}_{3}}-C-\ddot{N}{{H}_{2}} \\
\end{matrix}}}\,$

$\underset{Ethyl\,\,acetoacetate}{\mathop{\begin{matrix}
\,\,\,\,\,O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,O \\
\,\,\,\,\,\,||\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|| \\
{{C}_{2}}{{H}_{5}}\ddot{O}-C-C{{H}_{2}}-C-C{{H}_{3}} \\
\end{matrix}}}\,$

$\mathrm{As}-\mathrm{NH}_{2}$ is more basic than $\mathrm{RO}^{-}$ hence acetamide has more polar $\begin{matrix}
\backslash \\
/ \\
\end{matrix}C=O$ group than $\mathrm{OC}_{2} \mathrm{H}_{5}$ group in ethyl acetoacetate.

Hence assertion and reason both are true and reason is correct explanation of assertion.
