Which among the following is least covalent in nature?

Options

  1. ANF ₃
  2. BBiF ₃
  3. CPF ₃
  4. DSbF ₃

Correct answer

B. BiF ₃

Step-by-step solution

According to the Fajan's rule, smaller the cation, stronger is the covalent bond it forms, more is the covalent nature. Bi forms largest cation in the group. So, it is least covalent in nature.
