A) \[{{F}_{2}}\]
B) \[C{{l}_{2}}\]
C) \[B{{r}_{2}}\]
D) \[{{I}_{2}}\]
Correct Answer: C
Solution :
As the size increases bond length increases, thus bond dissociation energy decreases. Molecule Bond dissociation energy \[{{F}_{2}}\] 158.8 \[C{{l}_{2}}\] 242.6 \[B{{r}_{2}}\] 192.8 \[{{I}_{2}}\] 151.1 However, the dissociation energy of fluorine is less because of its small size. Hence, \[\text{C}{{\text{l}}_{\text{2}}}\] has the highest bond dissociation energy
