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.
