(B)Ionisation enthalpy
(C)Hydration enthalpyCorrect
(D)Electron affinity

Answer: (C)

Solution

Although fluorine's electron affinity is actually lower than chlorine's (due to inter-electronic repulsion in its small 2p orbitals), fluorine's overall oxidizing power in aqueous solution (standard reduction
