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
Options
- AA > C > B > D
- BB > A > C > D
- CA > B > C > D
- DA > B > D > C
Correct answer
C. A > B > C > D
Step-by-step 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
