Which of the following compounds would be most ionic in character?
Options
- AP b C l 4
- BP b C l 2
- CS n C l 4
- DS n C l 2
Correct answer
B. P b C l 2
Step-by-step solution
The lower valencies are more ionic, because the radius of M 2 + is greater than that of M 4 + and according to Fajan's rules, the smaller the ions, the greater is the tendency to covalency. P b C l 2 is more ionic than S n C l 2 , because Pb has lower electronegativity than that of Sn.
