Question: What is the coordination number of hydrogen in the complex [Ni(H2)6]?

Options:

Correct Answer: 6

Solution:

In the complex [Ni(H2)6], the coordination number of hydrogen is 6, as there are six hydrogen ligands coordinated to nickel.

What is the coordination number of hydrogen in the complex [Ni(H2)6]?

What is the coordination number of hydrogen in the complex [Ni(H2)6]?

Step 1: Identify the complex given in the question, which is [Ni(H2)6].
Step 2: Understand that 'H2' refers to a diatomic hydrogen molecule, which acts as a ligand.
Step 3: Count the number of hydrogen ligands in the complex. Here, there are 6 'H2' molecules.
Step 4: Recognize that each 'H2' molecule counts as one ligand, so 6 'H2' molecules mean there are 6 ligands in total.
Step 5: Conclude that the coordination number is the total number of ligands attached to the central metal (nickel in this case).
Step 6: Therefore, the coordination number of hydrogen in the complex [Ni(H2)6] is 6.

Coordination Number – The coordination number refers to the number of ligand atoms that are directly bonded to a central metal atom in a complex.
Ligands – Ligands are ions or molecules that can donate a pair of electrons to the central metal atom, forming coordinate bonds.
Complex Ions – Complex ions consist of a central metal atom bonded to surrounding ligands, which can be neutral or charged.
