Q. Arrange the following bonds according to their average bond energies in descending order:
$C - Cl, C - Br, C - F, C - I$

JEE MainJEE Main 2020The p-Block Elements - Part2

Solution:

Bond length order in carbon halogen bonds are in the order of $C - F < C - Cl < C - Br < C - I$
Hence, Bond energy order
$C - F > C - Cl > C - Br > C - I$
