Chapter 20, Problem 21P

Name the following:

Chapter 20, Problem 21P, Name the following:

(a)

Expert Solution
Check Mark
Interpretation Introduction

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 2methylazetidine.

Explanation of Solution

The structure of the given compound is shown below.
