Question

Define monodentate ligands and give example.

Hint:

"Mono" means one and "dentate" refers to teeth/binding sites. So, "one-toothed" ligands bind at one site only.

Answer 1

Definition: A monodentate (or unidentate) ligand is a ligand that has only one donor atom capable of forming a coordinate bond with the central metal ion.
Examples:
1. Ammonia (:NH$_3$) - The Nitrogen atom is the donor.
2. Water (H$_2$O:) - The Oxygen atom is the donor.
3. Chloride ion (Cl$^-$) - Acts as a donor.
