The bond length (pm) of F ₂, H ₂, Cl ₂ and I ₂ , respectively is

Options

  1. A144,74,199,267
  2. B74,144,199,267
  3. C74,267,199,144
  4. D144,74,267,199

Correct answer

B. 74,144,199,267

Step-by-step solution

As the size of halogen atom increase, the bond length X-X bond in X₂ molecule increase from F ₂ to I ₂ hence, the correct answer is (2).
