A) tetrahedral
B) trigonal
C) octahedral
D) pyramidal
Correct Answer: C
Solution :
As per formula,\[\text{radius}\,\text{=}\frac{\text{radius}\,\text{of}\,\text{cation}}{\text{radius}\,\text{of}\,\text{anion}}\] \[\,\text{=}\frac{94}{146}=0.643\] Since the value is between 0.414 - 0.732 hence the coordination no. will be 6 and geometry will be octahedral.You need to login to perform this action.
