Chapter 19, Problem 2QAP
Interpretation Introduction

(a)

Interpretation:

To determine the ligand and their charges in [Cd (en)(SCN)2(OH)2-].

Concept introduction:

Coordination compounds are those in which a transition metal atom is bonded to a ligand which can be neutral, cation or anion. The transition metal element is enclosed within a bracket and a charge is present on the ion to balance the charge present on the ligands.

A ligand is an atom or a group of atoms or an anion that has an unshared pair of electrons and thus it can act as a Lewis base. It can donate its pair of electrons to the metal atom to form a coordinate bond with the transition metal atom.

Interpretation Introduction

(b)

Interpretation:

To determine the oxidation state of Cadmium in [Cd (en)(SCN)2(OH)2-].
