The given chemical structure has to be named.

Concept Introduction:

The nomenclature of the chemical structures:

A molecular formula describes the total number and types of the atoms in a molecule, whereas chemical structures describe the arrangement of atoms in a compound.

International Union of Pure and Applied Chemistry gave guidelines to write the chemical name of molecules. IUPAC names are totally different from common names because IUPAC names are applied at international level and it comprises suffix, prefix, numbers and other priority rules. The numbering starts from the side of substituent; if more than one substituent groups are present then these are cited alphabetically in the compound’s name.

Organic Chemistry, Chapter 20, Problem 21P , additional homework tip 4

Figure 4

The compounds that comprise saturated six membered rings with a nitrogen atom are named as piperidines. The ethyl and methyl substituents are present at the second and fifth carbon atoms respectively. Therefore, the name of the compound shown in figure is 2−ethyl−5−methylpiperidine.
