Name the following:
(a)

Interpretation:
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.
Answer to Problem 21P
The name of the given compound is
Explanation of Solution
The structure of the given compound is shown below.
Figure 1
The compounds that comprise the saturated four membered rings are named as azetidines. The methyl substituent is present at the second carbon atom. Therefore, the name of the compound shown in figure is
