Bond dissociation energy of F(2) is less...

Bond dissociation energy of `F_(2)` is less that of `Cl_(2)` give reason.

Text Solution

Verified by Experts

Atomic size of `F` atom is less than `Cl` ,hence bond length `F-F` is less than `Cl-Cl`. Thus the `lp-lp` repulsion in `F-F` molecule is much larger than `Cl-Cl` molecules . Hence `F-F` bond is weaker than `Cl-Cl` bond dissociation energy of `F_(2)` is less than that of `Cl_(2)`.
