Which of the following compounds is the strongest base

Options

(a) Methylamine
(b) Aniline
(c) Ammonia
(d) N-methyl aniline

Correct Answer:

Methylamine

Explanation:

Due to + I-effect of -CH₃ group, in methyl amine the electron density over ‘N’ atom is more than in ammonia, atom in aniline as well as in N-methylaniline is less than in ammonia. Therefore CH₃ – NH₂ (methyl amine) is the strongest base among these.
