Choose the correct option from the following

Options

  1. AKF is more covalent than KI
  2. BSnCl 4 is less covalent than SnCl 2
  3. CLiF is more covalent than KF
  4. DZnCl 2 is less covalent than NaCl

Correct answer

C. LiF is more covalent than KF

Step-by-step solution

Fajan's rules were developed based on the concept, "the greater the polarization of anion, the greater is the covalent nature". The polarizing power increases with increase in the size of cation i.e. smaller cations are very effective in the polarization of anion. Polarizability of an anion is the tendency of an anion to undergo polarization. It indicates the easiness with which an anion undergoes distortion in presence of a cation. Due to polarization of anion and the increase in covalent nature. Lithium ion i
