Chapter 19, Problem 2QAP

Interpretation Introduction

(a)

Interpretation:

To determine the ligand and their charges in $\left[\text{Cd }{\left(\text{en}\right)}_{}{\left(\text{SCN}\right)}_{\text{2}}{\left(\text{OH}\right)}_{\text{2}}{}^{\text{-}}\right]$.

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 $\left[\text{Cd }{\left(\text{en}\right)}_{}{\left(\text{SCN}\right)}_{\text{2}}{\left(\text{OH}\right)}_{\text{2}}{}^{\text{-}}\right]$.

(c)

Interpretation:

To determine formula of the magnesiumsalt of $\left[\text{Cd }{\left(\text{en}\right)}_{}{\left(\text{SCN}\right)}_{\text{2}}{\left(\text{OH}\right)}_{\text{2}}{}^{\text{-}}\right]$.
