The low bond energy of fluorine molecule is best explained by

Options

A. the high electronegativity of fluorination
B. the small size of fluorine
C. the attainment of noble gas configuration by fluorine
D. repulsion by lone pairs on fluorine.

Answer

D

Explanation

Due to smaller bond length of fluorine, the lone pairs are nearer and so interelectronic repulsions between the lone pairs is more so it has low bond energy
