Solution:

$F_{2}$ is expected to have highest bond energy but the correct decreasing order is $Cl_{2} > Br_{2} > F_{2}$ because of fluorine atom has very small size due to which there is a high inter electronic repulsion between two fluorine atoms so the bond between two fluorine gets weaker and need less energy.
