Q.In which of the following arrangements, the order is NOT according to the property indicated against it?

Li < Na < K < Rb

(Increasing metallic radius)

I < Br < F < Cl

(Increasing electron gain enthalpy)

B < C < N < O

(Increasing first ionization enthalpy)

Al^{3+} < Mg^{2+} < Na^+ < F^-

(Increasing ionic size)

The correct solution involves applying the fundamental concept to derive the final value step by step...
