Which of the following has highest bond-dissociation energy?

a)F-F
b)Cl-Cl
c)Br-Br
d)I-I

Answered by admin @ 23/08/2021

The answer is a Because fluorine being smallest among halogens has highest electronegativity and thus binds strongly to another fluorine atom.Hence F-F bond requires higher amount of energy to break the bond.
