Chapter 21, Problem 21.79SP

Interpretation Introduction

(a)

Interpretation:

The systematic name of ${\left[{\text{AuCl}}_{\text{4}}\right]}^{\text{-}}$ needs to be determined.

Concept introduction:

The chemical formula is used to indicate the structure of a chemical substance. The formula contains the element with the number of the atoms denoted as subscripts. The naming is done by using the method of the IUPAC system that has certain rules to be followed.

Interpretation Introduction

(b)

Interpretation:

The systematic name of ${\left[{\text{Fe(CN)}}_6\right]}^{\text{4-}}$ needs to be determined.

Concept introduction:

The compounds are indicated by using chemical structures, that are denoted by using the element with the number of atoms and indicated as subscripts. There is the use of brackets and parentheses to separate different molecules. Even roman numerals are used to indicate the oxidation state.

Interpretation Introduction

(c)

Interpretation:

The systematic name of ${\left[{\text{Fe(H}}_{\text{2}}{\text{O)}}_{\text{5}}\text{NCS}\right]}^{2+}$ needs to be determined.

Concept introduction:

Compounds are named by using the chemical formula and the naming of the compound is by using the IUPAC method. The elements are denoted by using the elemental formula and the number of atoms is indicated as subscripts. They are brackets and parentheses to indicate the repetition of molecules.

Interpretation Introduction

(d)

Interpretation:

The systematic name of ${\left[{\text{Cr(NH}}_3{\text{)}}_{\text{2}}{{\text{(C}}_2{\text{O}}_4\text{)}}_{\text{2}}\right]}^{-}$ needs to be determined.

Concept introduction:

The chemical structure denotes chemical compounds wherein the elements denote each atom. The number of atoms is denoted as subscripts. The atoms are denoted within brackets and parentheses. Roman numerals are used to indicate the oxidation state.
