The correct order of covalent nature of alkali metal chlorides is:
A. LiCl < NaCl < KCl < RbCl < CsCl
B. CsCl < NaCl < KCl < RbCl < LiCl
C. LiCl > NaCl > KCl > RbCl > CsCl
D. LiCl = NaCl = KCl = RbCl < CsCl
Answer:C
The correct order of covalent nature of alkali metal chlorides is:
A. LiCl < NaCl < KCl < RbCl < CsCl B. CsCl < NaCl < KCl < RbCl < LiCl C. LiCl > NaCl > KCl > RbCl > CsCl D. LiCl = NaCl = KCl = RbCl < CsCl
Explanation: The covalent nature decreases with increase in the size of cation since the polarizing power decreases with increase in the size.
