Chemical Bonding And Molecular Structure Question 390
Question: Polarization is the distortion of the shape of an anion by an adjacently placed cation. Which of the following statements is correct [NCERT 1982]
Options:
A) 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
Show Answer
Answer:
Correct Answer: A
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.
