Question

Which of the following represents a chelate ligand?

Options

• OH^–

• H₂O

• Cl^–

• NH₂CH₂CH₂NH₂

Answer 1

NH₂CH₂CH₂NH₂

Explanation:

When a di- or polydentate ligand uses its two or more donor atoms to bind to a single metal atom/ion, it is said to be a chelate ligand. Ethane-1, 2-diamine (NH₂CH₂CH₂NH₂) can act as a chelate ligand as it is a didentate ligand.
