Nomenclature Of Coordination Compounds

The hybridization state of the Fe atom in these species can be determined by considering the geometry of the complex and the ligands involved. For these complexes, the hybridization is , as seen in octahedral complexes.

When reacts with NaOH, it forms a complex ion , as the hydroxide ions and water molecules coordinate with the aluminium ion.

Step 1: Understanding Coordination Number.
The coordination number is the number of ligands bonded to the central metal atom. In , the coordination number of cobalt is 6 because there are six ammonia molecules as ligands.
Step 2: Conclusion.
The correct answer is (D), +6.

Step 1: Understanding Fac & Mer Isomerism.
Fac-mer isomerism occurs in octahedral complexes where the ligands are arranged in a specific way. The complex has two bidentate ligands (ethylenediamine), which can lead to fac-mer isomerism depending on their spatial arrangement.
Step 2: Conclusion.
The correct answer is (B), .

Step 1: The spin-only magnetic moment is given by: where is the number of unpaired electrons. The value of 2.82 B.M. corresponds to , indicating that the complex has two unpaired electrons.
Step 2: The complex has the required configuration to give the spin-only magnetic moment of 2.82 B.M.

Final Answer:

When copper sulfate reacts with potassium cyanide, a coordination complex is formed.
Final Answer:

The coordination compound with five ammonia molecules, one nitro group, and two chlorine ions gives the ionic formula , which dissociates in water to give three ions.
Final Answer:

A paramagnetic complex has unpaired electrons. has unpaired electrons in the d-orbital, making it paramagnetic.
Final Answer:
