Chapter 22, Problem 8QP

Interpretation Introduction

Interpretation:

The terms coordination compound, ligand, donor atom, coordination number, and chelating agent need to be defined.

Concept introduction:

A compound or ion with a centrausually metallic atom or ioncombined by coordinate bonds with a definite number of sorrounding ions groups or molecules is termed as coordination compound.

Lewis bases are ligands thatconsist of a lone pair of electrons to donate.

Donor atoms have energy orbitals thathave one or more electrons.

The number of atoms, ions or moleculesthat a central atom or ion holds as its nearest neighbors in a complex or coordination compound is known as coordination number. It is otherwise known as ligancy.

Chelating agents are chemical compounds that react with metal ions to form stable water soluble complex.
