Answer 2

Answer:

Assertion fluorine has greater electron affinity than chlorine reason fluorine is stronger oxidising agent than chlorine

The most important reason for this phenomenon is much greater heat of hydration of F− than Cl− which compensates for the lower electron affinity of F than of Cl. Hence, fluorine is the strongest oxidizing agent.
