Bond enthalpy of fluorine is lower than that of chlorine why ? – InterviewSolution

1.	Bond enthalpy of fluorine is lower than that of chlorine why ?
Answer» Solution :BOND enthalpy of `F - F` is smaller DUE to greater REPULSIVE interactions between the lone pair of one F ATOM with those of other. The repulsive interaction arise due to greater concentration of electron density on each F atom because of its extremely SMALL size.
