Q. The correct order of bond dissociation enthalpy of halogens is :

JEE MainJEE Main 2021Classification of Elements and Periodicity in Properties

Solution:

Correct order of bond dissociation enthalpy of halogens is $Cl _{2}> Br _{2}> F _{2}> I _{2}$.
Due to inter electronic repulsions $F - F$ bond becomes weak and easily broken.
