Which of the following species contains three bond pairs and one lone pair around the central atom?

Options

  1. AH ₂ O
  2. BBF ₃
  3. CNH ₂⁻
  4. DPCl ₃

Correct answer

D. PCl ₃

Step-by-step solution

(A) where, bp = bond pairs, and ( lp = ) lone pairs. (b) (c) (d) Thus, in PCl ₃ , the central atom P has three bond pairs and one lone pair.
