The bond energies of `F_2, Cl_2, Br_2 and I_2` are 155, 244, 193 and 151 kJ mol respectively. The weakest bond will be in

A

`Br_2`

B

`Cl_2`

C

`F_2`

D

`I_2`

Text Solution

Verified by Experts

The correct Answer is:
D

Lesser the bond energy, weaker is the bond. Thus, I-I bond with lowest bond energy `(151 kJ mol^(-1))` is the weakest bond
