Which ligand classification is based on the number of donor atoms present?

Monodentate, bidentate, and tridentate (correct)

Bidentate, tridentate, and pentadentate

Monodentate, tetradentate, and hexadentate

Tetradentate, pentadentate, and hexadentate

Which of the following is an example of a bidentate ligand?

NO

H₂O

CO₂ (correct)

Why do metal carbonyls effectively obey the EAN rule?

Due to their strong magnetic properties

Due to their high reactivity

Because they contain multiple donor atoms

Because they exist in a zero oxidation state (correct)
