Interpretation Introduction

(a)

Interpretation:

The complete IUPAC name of the given molecule is to be written.

Concept introduction:

In an aldehyde, one side to the alkyl groups or aryl groups and on the other side to an H atom, the carbonyl carbon $\text{C=O}$ is bonded. In the nomenclature of aldehyde, suffix “one” is added to the IUPAC name.

In the IUPAC name, the root name indicates the longest carbon chain at the end of the compound’s name. The suffix ‘al’ refers to the carbonyl group, ($\text{C=O}$), functional group. Any other alkyl groups, attached to the carbonyl carbon atom in an aldehyde, are treated as substituents and added in the name as a prefix. Other, lower priority, functional groups are listed as prefixes, along with numbers indicating their positions on the longest carbon chain. Prefixes, di, tri, etc., are used to denote the number of identical substituents. The substituents are written in alphabetical order when writing the IUPAC name.
