Question

Polarisation may be called the distortion of the shape of an anion by an adjacently placed cation.which of the following statements is correct

A minimum polarization is brought about by a cation of low radius

B a large cation is likely to bring about the largedegree of polarization

C maximum polarisation is brought about a cation of highcharge

D a small anion is likely to undergo a large degree of polarization

Answer 1

• Correct Answer: C

  Solution :

  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.
