Question

Polarisation power of cation is maximum when​

Answer 1

Answer:

Now, among all the ions given to us, the Al+3 ion is the smallest in size because it has lost 3 electrons so it becomes very small as compared to other ions (the effective nuclear charge increases to a maximum amount). So, It will have maximum polarizing power.
