Assertion : Bond dissociation energy is $F_{2} > Cl_{2}$ Reason : $Cl_{2}$ has more electronic repulsion than $F_{2}$ .

Options:

Answer:

Solution:

Bond dissociation energy is $F_{2} < Cl_{2}$ because of relatively large electron-electron repulsion among the lone pairs in $F_{2}$ molecule where they are much closer to each other than in $Cl_{2}$ .
