Chemistry Question on Chemical Reactions
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)
Answer
(A) > (B) > (C) > (D)
Explanation
Solution
The correct option is(C): (A) > (B) > (C) > (D)
Covalent character ∝ polarising power of cation
Correct decreasing order of covalent character
LiCl > NaCl > KCl > CsCl
