Why does aniline have a higher pKb value compared to ammonia?

Options

  1. AAniline has a stronger inductive effect.
  2. BAniline has a resonance-stabilised structure.
  3. CAniline has a larger molar mass.
  4. DAniline has a higher electronegativity.

Correct answer

B. Aniline has a resonance-stabilised structure.

Step-by-step solution

Aniline has a resonance-stabilized structure with multiple resonating forms, making it more stable and less basic compared to ammonia.
