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

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

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Bond dissociation energy is $F_{2} < C l_{2}$ 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 $C l_{2}$

Q. Assertion: Bond dissociation energy is F2​>Cl2​. Reason: Cl2​ has more electronic repulsion than F2​.
