Bond enthalpy of fluorine is lower than ...

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

Text Solution

Verified by Experts

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.
