F_2 has lower bond dissociation enthalpy than Cl_2. Why? – InterviewSolution

1.	F_2 has lower bond dissociation enthalpy than Cl_2. Why?
Answer» Solution : Fluorine is expected to have the highest value of bond DISSOCIATION ENERGY because it has the smallest size and highest eletronegativity value among HALOGENS. DUE to its extremely small size, the repulsions among shared electrons take place which reduces its bond dissociation enthalpy, which is LESS than that of `Cl_2`.
