The charge/ size ratio of a cation determines its polarizing power. Which one of the following sequences represents the increasing order of the polarizing power of these cationic species, K + , Ca 2+ , Mg 2+ , Be 2+ ?
Text Solution
Verified by ExpertsThe correct answer is:
A
High charge and small size of the cations increases polarisation.
As the size of the given cations decreases as
K + > Ca 2+ > Mg 2+ > Be 2+
Hence, polarising power increases as
