Fluorine is very reactive because its bond dissociation energy is less

1.	Fluorine is very reactive because its bond dissociation energy is less. Why bond energy is less in F_2?
Answer» Solution :FLUORINE ATOM has seven valence electrons. One electron each of two F ATOMS are shared to form the single bond. Each F atom has thre IONE pairs. The Ione pair Ione pair repulsion are predominent in `F_(2)` molecule. Hence bond energy in `F_(2)` is less.
