STANDARD Chemistry Geometry of Complexes MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following sets of examples and geometry of the compounds is not correct?
A
Octahedral - [Co(NH₃)₆]³⁺, [Fe(CN)₆]³⁻
B
Square planar - [Ni(CN)₄]²⁻, [Cu(NH₃)₄]²⁺
C
Tetrahedral – [Ni(CO)₄], [ZnCl₄]²⁻
D
Trigonal bipyramidal - [Fe(NH₃)₆]²⁺, [CuCl₄]²⁻
Correct Answer
Option D
Detailed Explanation
[CuCl₄]²⁻ is actually tetrahedral, not trigonal bipyramidal. The geometry of [Fe(NH₃)₆]²⁺ is octahedral.
