Question

2. The correct order of .polarising ability of cations
of Alkaline earth metals is
1) Be2+> Ca2+> Mg2+> Ba2+
2) Be2+ < Mg2+> Ca2+ = Ba2+
3) Be2+ < Mg2+> Ca2+ < Ba2+
4) Ba2+< Ca2+<Mg2+ < Be2+

Answer 1

Answer:

Correct option : D

Explanation :

Polarising ability is directly proportional to the charge of cation and inversely properly to radius of cation.
