Which one of the following halogens has the highest bond energy ?

A

`F_2`

B

`Cl_2`

C

`Br_2`

D

`I_2`

Text Solution

Verified by Experts

The correct Answer is:
B
Shorter the bond, stronger the bond, more its bond dissociation energy. However bond dissociation energy of `Cl_2` is more than `F_2`. This is despite the fact that F-F bond is shorter than Cl-Cl bond. Correct order of bond energies is `Cl_2 gt Br_2 gt F_ 2 gt I_2`
