The bond length (pm) of \(\mathrm{F}_2, \mathrm{H}_2, \mathrm{Cl}_2\) and \(\mathrm{I}_2\), respectively is
- A \(144,74,199,267\)
- B \(74,144,199,267\)
- C \(74,267,199,144\)
- D \(144,74,267,199\)
Answer & Solution
Correct Answer
(B) \(74,144,199,267\)
Step-by-step Solution
Detailed explanation
As the size of halogen atom increase, the bond length \(X-X\) bond in \(X_2\) molecule increase from \(\mathrm{F}_2\) to \(\mathrm{I}_2\) hence, the correct answer is (2).
