Which one of the following molecular hydrides acts as a Lewis acid ?

Options

  1. ANH ₃
  2. BH ₂ O
  3. CB ₂ H ₆
  4. DCH ₄

Correct answer

C. B ₂ H ₆

Step-by-step solution

Key Idea:- Electron deficient molecules behave as Lewis acid. Among the given molecules, only diborane is electron deficient, ie, does not have complete octet. Thus, it acts as a Lewis acid. NH ₃ and H ₂ O being electron rich molecules behave as Lewis base.
