Interpretation Introduction

Interpretation:

The given functional class IUPAC names are to be converted into their respective substitutive names.

Concept introduction:

Aldehydes and ketones contain carbonyl $\left(\text{C=O}\right)$ functional group in their parent chain and are named by adding suffix –al and –one to the name of the parent alkane.

The systematic naming of organic compound is given by IUPAC. The naming of organic compound is done in such a way that the structure of organic compound is correctly interpreted from the name. The hydrocarbons or groups that are attached to the longest chain are called substituents and they are written as prefix in alphabetical order.

The first step in the naming of ketone is the finding of longest parent chain that contains a carbonyl group. The second step is changing of -e ending of the parent alkane to the suffix -one. The third step is numbering of chain to give the least number to carbonyl carbon, and using the general rules of nomenclature.
