Question

Fluorine is a stronger oxidising agent than chlorine in aqueous solution. This is attributed to many factors except
A. Heat of dissociation
B. Electron affinity
C. Ionisation potential
D. Heat of hydration

Answer 1

Correct Answer - C
Greater reactivity of `F_2` than `Cl_2` in aqueous solutions is not due to ionisation potential. This is because halogens `(Cl_2, F_2)` are good oxidising agents i.e., their reactivity depend upon their ability to take up an electron and not to give any electron.
