Question

The complex of Ni\(^{2+}\) ion and dimethyl glyoxime contains ____ number of Hydrogen (H) atoms.

Hint:

When determining the number of hydrogen atoms in a complex, consider the number of hydrogen atoms in the ligands involved in the complexation.

Answer 1

Correct Answer: 6

The complex in question is Ni(dimethylglyoxime)₂. Each dimethyl glyoxime ligand, often abbreviated as dmgH₂, contains two hydrogen atoms. The general formula for the ligand is (CH₃C=NOH)₂, representing dimethyl glyoxime as a monobasic bidentate ligand.

Step-by-step breakdown:

• The dimethyl glyoxime molecule is represented as (CH₃C=NOH)₂.
• Each dmgH₂ contains two hydrogen atoms.
• The complex Ni(dmgH)₂, where Ni²⁺ is coordinated with two dmgH₂ ligands.
• Therefore, the total number of hydrogen atoms contributed by the two ligands is 2 (hydrogens per dmgH₂) × 3 (number of dmgH₂ ligands) =  hydrogen atoms.

Thus, the number of hydrogen atoms is 6.
