Solution
The correct options are ANa<K<Rb BNa>Mg>Al CF−<Cl−<Br−<I− DMg<Ca<Sr All the options (A to D) represent the correct order of reducing property.
(A) Na<K<Rb: On moving down the group, the electropositive character increases and the reducing character increases.
(B) Na>Mg>Al: In a period from left to right, the electropositive character decreases and the reducing character decreases.
(C) F−<Cl−<Br−<I−: With the increase in the size of halide ion, the electropositive character increases and the reducing character increases.
(D) Mg<Ca<Sr: On moving down the group, the electropositive character increases and the reducing character increases.
