Question

What is the number of donor atoms in dimethylglyoximato ligand?

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is B

$2$

Explanation for correct option:

B: Dimethylglyoxime Ligand:

• Dimethylglyoxime is a bidentate ligand.
• “When a ligand can bind through two donor atoms, the ligand is said to be bidentate.”
• The structure of Dimethylglyoxime ligand:

• As this ligand is a bidentate ligand, thus it has two donor atoms, and they are both the Nitrogen $\left(\mathrm{N}\right)$ atoms.

The explanation for incorrect options:

Since there are two donor atoms in the case of Dimethylglyoxime ligand as it is a bidentate ligand. Thus Options A, C, and D stand incorrect.

Hence, the correct option is B i.e. $2$ donor atoms.
