WebMar 11, 2024 · The bond dissociation energy of $\left ( { {F_2}} \right)$ is exceptionally less because Fluorine has small atomic size due to which the electrons are held in a compact volume, consequently there is strong repulsion amongst non-bonded electrons. Hence the bond becomes weak and the dissociation energy is lowest amongst other … WebNov 16, 2024 · Hello! If you are comparing the bond strength of diatomic halogens, we can compare F2 to Cl2. The bond dissociation energy of F2 is less than Cl2 because fluorine has a high electronegativity, resulting in F−F repelling each other and having lesser bond dissociation enthalpy than Cl2 since Cl is less electronegative than F.
