(a)

Interpretation Introduction

Interpretation:

Systematic name for ${\text{[Pt(en)}}_{\text{3}}{\text{](NO}}_{\text{3}}{\text{)}}_{\text{4}}$ has to be given.

Concept Introduction:

There are certain rules to be followed while naming a transition metal complex.  They are listed below.

• Name of the cation is written first followed by the anion.
• In any neutral complex or complex ion, the name of ligand is written first followed by the metal to which the ligands are attached.  If the complex contains more than one type of ligands, then they are written in alphabetical order.
• Negative ligands names are ended with the letter “o” while the name is given as such for the neutral ligand molecules.
• Number of ligands present in the complex is denoted by adding Greek prefix.
• Ordinary name for the metal is used if the complex ion is cation or neutral while the name of the metal is ended with “-ate”, if the complex ion is an anion.
• Oxidation state of the metal that is present in the complex is indicated by the Roman numeral following the name of the metal.
