Arrange the following in the decreasing order of their covalent character :

(A) LiCl

(B) NaCl

(C) KCl

(D) CsCl

Choose the most appropriate answer from the options given below

  1. A>C>B>D
  2. B>A>C>D
  3. A>B>C>D
  4. A>B>D>C

Solution

Lithium chloride is the alkali metal chloride which is most covalent in nature. This is due to the small size and high polarising power of lithium. That is, smaller the cation, greater is the polarising power and hence, greater is the covalent character.

So order of covalent character will be CsCl<RbCl<NaCl<LiCl
