A) \[C{{l}_{2}}>B{{r}_{2}}>{{F}_{2}}>{{I}_{2}}\]
B) \[C{{l}_{2}}>{{F}_{2}}>B{{r}_{2}}>{{I}_{2}}\]
C) \[{{I}_{2}}>B{{r}_{2}}>C{{l}_{2}}>{{F}_{2}}\]
D) \[{{I}_{2}}>B{{r}_{2}}>{{F}_{2}}>C{{l}_{2}}\]
Correct Answer: A
Solution :
The correct order of bond energy is \[C{{l}_{2}}>B{{r}_{2}}>{{F}_{2}}>{{I}_{2}}\] \[\text{210}\,\text{kJ}\,\text{mol}\,\,\text{}\,\,\text{158}\,\text{kJ/mol}\] \[\text{}\,\text{126}\,\text{kJ/mol}\,\text{118}\,\text{kJ/mol}\]
