MCQ

Polarization is the distortion of the shape of an anion by an adjacently placed cation. Which of the following statements is correct

✓
Maximum polarization is brought about by a cation of high charge
B
Minimum polarization is brought about by a cation of low radius
C
A large cation is likely to bring about a large degree of polarization
D
A small anion is likely to undergo a large degree of polarization

✓

Answer

Correct option: A.

Maximum polarization is brought about by a cation of high charge

(a) According to Fajan’s rule, polarisation of anion is influenced by charge and size of cation more is the charge on cation, more is polarisation of anion.
