Question

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:

(A) (A) > (C) > (B) > (D)
(B) (B) > (A) > (C) > (D)
(C) (A) > (B) > (C) > (D)
(D) (A) > (B) > (D) > (C)

Prashant Kotian · Accepted Answer

Correct answer: B) (B) > (A) > (C) > (D). Covalent character is directly proportional to the polarizing power of cation. Smaller the size of cation, the greater the covalent character. Correct decreasing order of covalent character- LiCl > NaCl > KCl > CsCl
