Account for the following statement- pK b of aniline is more than that of methylamine.

Options

  1. AAniline has a larger conjugated pi system.
  2. BIn aniline, the electron pair on nitrogen atom is involved in conjugation with ring and is less available for
  3. CAniline has a higher molecular weight.
  4. DAniline has a stronger hydrogen bond donor capacity.

Correct answer

B. In aniline, the electron pair on nitrogen atom is involved in conjugation with ring and is less available for

Step-by-step solution

Correct Option is : (B) In aniline, the electron pair on nitrogen atom is involved in conjugation with ring and is less available for protonation than in methyl amine. Therefore, pK b value of aniline is more than that of methylamine and aniline is less basic
