Question

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

• A. Minimum polarization is done by a cation of small size.
• B. Maximum polarization is done by a cation of high charge
• C. A smaller anion is likely to undergo high degree of polarization
• D. A large cation is likely to bring large degree of polarization

Answer 1

The correct option is B

Maximum polarization is done by a cation of high charge

According to Fajans rules, polarization will be favoured by small size of cation, large size of anion and high charge of cation and anion.
