Polarization means "the distortion of the shape of an anion by an adjacently placed cation". Which of the following statements about polarization is correct
Options
- AMaximum polarization is brought about by a cation of high charge
- BMinimum polarization is brought about by a cation of low radius
- CA large cation is likely to bring about a large degree of polarization
- DA small anion is likely to undergo a large degree of polarization
Correct answer
A. Maximum polarization is brought about by a cation of high charge
Step-by-step solution
According to Fajan's rule, polarisation of anion is influenced by charge and size of cation more is the charge and small size of cation causes more polarisation of anion having larger size and greater charge.
