Question
The charge/size ratio of a cation determines its polarizing power. Which one of the following sequences represents the increasing order of the polarizinig order of the polarizing power of the cationic species, K+, Ca2+, Mg2+, Be2+?
Options
A.Mg2+ ,Be2+ ,K+ ,Ca2+
B.Be2+ ,K+ ,Ca2+ ,Mg2+
C.K+ ,Ca2+ ,Mg2+ ,Be2+
D.Ca2+ ,Mg2+ ,Be2+ ,K+
Solution
Higher the charge/size ratio, more is the polarizing power.
∴ K+ < Ca2+ < Mg2+ < Be2+
Hence, (3) is correct.
∴ K+ < Ca2+ < Mg2+ < Be2+
Hence, (3) is correct.
