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.

To determine the total number of hydrogen atoms in the complex, we need to look at the structure of dimethyl glyoxime. The molecular formula of dimethyl glyoxime is C\(_4\)H\(_6\)N\(_2\)O\(_2\), which includes:

• 2 hydrogen atoms from the methyl groups (-CH\(_3\))
• 2 hydrogen atoms from the hydroxyl groups (-OH)
• 2 additional hydrogen atoms are part of the glyoxime structure, not part of any specific functional group.

Thus, the total number of hydrogen atoms in the complex is 6, considering the contribution of each group.
