Which of the following metal halide is more covalent?
Options
- AS n C l 2
- BP b C l 2
- CS b C l 3
- DS b C l 5
Correct answer
D. S b C l 5
Step-by-step solution
Key Idea Fajan’s rules help in predicting the covalent character in bond. S b C l 5 metal halide is more covalent than other given options. It can be explained on the basis of Fajan’s rule. Higher the charge on the cation, greater is its polarising power. In S b C l 5 , Antimony (Sb) is in + 5 oxidation state. It has maximum polarising power. Hence, possess higher covalent character.
