Chapter 21, Problem 7RQ

Interpretation Introduction

Interpretation:

The classification of given ligands based on the number of donor atoms, i.e. monodentate, bidentate, or polydentate is to be determined.

Concept Information:

Complex ions are the ions formed by a metal atom at the center and the other nonmetal molecules or ions surrounding it.

Ligands are molecules or ions that are bonded to a metal ion with a coordinate covalent bond.

Lewis bases that donate a single pair of electrons to metal atom is called monodentate ligands, Lewis bases that donote two pairs of electons to metal atom is called bidentate and polydentate ligands range in the number of atoms used to bond to a central metal or ion.

Chelates are ring structures formed in complexes by polydentate ligands and metal ions.
