The order of covalent character of KF, KI, KCI is
Options
- AK Cl < KF < K I
- BK I < K Cl < K F
- CK F < K I < K C l
- DK F < K Cl < K I
Correct answer
D. K F < K Cl < K I
Step-by-step solution
As the size of anion size increases the ploarisability increases hence covalent character increases (As per Fajan's rules) order of covalent character is K F < K Cl < K I
