    How many of these elements have lower electron affinity than fluorine? Cl, S, O, N, P, Br, I, C

    (A) Chlorine has higher electron affinity than fluorine. (R) Chlorine is a poor oxidising agent than fluorine.

    Assertion: F atom has lower electron affinity than Cl atom. Reason: Additional electrons are reflected more effectively by 3p-electrons in Cl than 2p-electron in F atom.

    Statement-1 : Fluorine is a stronger oxidising agent than chlorine because Statement-2 : It has (i) low enthalpy of dissociation of F-F bond and (ii) high hydration energy.

    All though electron gain enthalpy of fluorine is less negatibe as compared to chlorine, Fluorine is stronger oxidizing agent then Chlorine becose of (i) Low Enthelpy of dissociation of F-F bond (iii) High Electron affinity of fluorine then chlorine
