Interpretation Introduction

Interpretation:

The formula for the given name of the complex compound has to be written.

Concept Introduction:

Systematic naming is the standard name given in a systematic way to a unique complex compound.

Systematic naming for the complex compound can be given based on the few important guidelines given below:

1. 1. The name of the ligand is followed by the name of the central metal cation of a complex compound.
2. 2. If there is more than one type of ligand, then their names are arranged in an alphabetical order.
3. 3. More than one ligand of the same type have to be numbered using the Greek prefixes such as di, tri, tetra, penta, and hexa which represent the count of 1,2,3,4.5 and 6 respectively.
4. 4. The roman numerals immediately following the metal ion name is the oxidation number of the metal.
5. 5. If the net charge of the complex ion is -ve, the central metal name should end with the suffix word –ate.  Whereas if the net charge of the complex ion is +ve, then the central metal name should end with the suffix word –um.
