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

Dimethyl glyoxime (C\(_4\)H\(_6\)N\(_2\)O\(_2\)) forms a complex with Ni\(^{2+}\), and each molecule of dimethyl glyoxime can bind to the Ni\(^{2+}\) ion by donating two nitrogen atoms. The hydrogen atoms in the molecule come from the two methyl groups and the two hydroxyl groups on the glyoxime. Thus, the total number of hydrogen atoms in the complex is 6.
