Interpretation Introduction

Interpretation:

The name of the given complex compound written by a student is correct or wrong has to be found.

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. When more than one same type of ligands are present, then the Greek prefixes such as di, tri, tetra, penta, and hexa are used to specify their count such as 1,2,3,4.5 and 6 respectively.
4. 4. The oxidation number of the metal is represented in roman numerals immediately following the metal ion name.
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.
