Which of the following is the strongest base?

  1. A \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2}\)
  2. B \(\mathrm{CH}_{3} \mathrm{NH}_{2}\)
  3. C \(\mathrm{NH}_{3}\)
  4. D \(\mathrm{CH}_{3} \mathrm{CONH}_{2}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\mathrm{CH}_{3} \mathrm{NH}_{2}\)

Step-by-step Solution

Detailed explanation

Basic nature of amine is due to the presence of lone pair of electrons on nitrogen atom which is available for the bond formation with Lewis acid. Due to \(+I\) effect of \(-\mathrm{CH}_{3}\) group, \(\mathrm{CH}_{3} \mathrm{NH}_{2}\) is the strongest base.
