A) tetrahedral
B) trigonal
C) octahedral
D) pyramidal
Correct Answer: C
Solution :
[c] As per formula, \[radius\text{ }ratio=\frac{radius\text{ }of\text{ }cation}{radius\text{ }of\text{ }amon}\] \[=\frac{94}{146}=0.643\] 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.
