Account for the following:Bond dissociation energy of F_2 is less than – InterviewSolution

1.	Account for the following:Bond dissociation energy of F_2 is less than that of Cl_2.
Answer» <P> Solution :Bond dissociation ENERGY of ` F_2` is less than that of `Cl_2` due to inter electronic repulsions in small size FLUORINE atoms. Chlorine has a large value of bond dissociation energy because of the possibility of multiple `p pi - dpi ` back BONDING involving filled p-orbitals and the vacant d-orbital.
