Question

'EA of Cl is the highest among the halogens, yet F is the strongest Oxidising agent'. Why?

Answer 1

$F_2$ is strong oxidizing agent than $Cl$, because-

$\left(i\right)$ Low enthalpy of dissociation of $F_2$, due to its small size, hydration energy is very high hence better oxidizing power.

$\left(ii\right)$ Flourine molecules have high repulsions between lone pairs on fatons. So, they have low dissociation enthalpy i.e., strong oxidizing power.
