Question

Which one of the following is the correct relation for polarising power?​

Answer 1

Answer:

According to Fajan's rule, higher the charge on the cation, more is its polarizing power. The next factor which is considered is the size of the cation. Smaller the size of the cation, higher is its polarizing power. Hence, the order of polarizing power is Cs+<K+<Mg2+<Al3+.

Answer 2

Answer

According to Fajan's rule, higher the charge on the cation, more is its polarizing power. The next factor which is considered is the size of the cation. Smaller the size of the cation, higher is its polarizing power. Hence, the order of polarizing power is Cs +<K +<Mg 2+<Al3+
