Which of the following set contains species having same angle around the central atom?

Options

  1. ASF ₄, CH ₄, NH ₃
  2. BNF ₃, BCl ₃, NH ₃
  3. CBF ₃, NF ₃, AlCl ₃
  4. DBF ₃, BCl ₃, BBr ₃

Correct answer

D. BF ₃, BCl ₃, BBr ₃

Step-by-step solution

BF ₃, BCl ₃, BBr ₃ are s p² hybridised. So, all have same structure and bond angle i.e. 120^ .
