Select the strongest base from the given compounds:
[A] p- \(\mathrm{NO}_2-\mathrm{C}_6 \mathrm{H}_4 \mathrm{NH}_2\)
[B] \(\mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}_2-\mathrm{NH}_2\)
[C] \(\mathrm{m}-\mathrm{NO}_2-\mathrm{C}_6 \mathrm{H}_4 \mathrm{NH}_2\)
[D] \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{NH}_2\)
- A [A]
- B [B]
- C [D]
- D [C]
Answer & Solution
Correct Answer
(B) [B]
Step-by-step Solution
Detailed explanation
The basicity of amines is determined by the availability of the lone pair of electrons on the nitrogen atom for protonation. In p-nitroaniline [A] and m-nitroaniline [C], the \(-\mathrm{NO}_2\) group is a strong electron-withdrawing group (EWG) that decreases the electron…
