NEET Chemistry Coordination Number MCQ Question
Which of the following statements about coordination numbers in coordination compounds is correct?
The coordination number of [Ni(NH3)4]2+ is 4.
The coordination number of [Fe(C2O4)3]3– is 4.
Both Pt and Ni have a coordination number of 6.
Didentate ligands always result in a coordination number of 4.
Correct Answer
Detailed Explanation
The coordination number of Ni in [Ni(NH3)4]2+ is indeed 4, while Pt has a coordination number of 6. The coordination number of [Fe(C2O4)3]3– is 6 due to the presence of didentate ligands. Didentate ligands can result in different coordination numbers depending on the specific complex.
