Introduction

In organic chemistry, the International Union of Pure and Applied Chemistry (IUPAC) is the governing body responsible for establishing a standardized nomenclature system for organic compounds. The IUPAC name of a compound is a unique identifier that provides information about its structure and composition. In this article, we will explore the IUPAC name of the given compound, COOH-CH2-C-O-O-CH3.

Understanding the Compound Structure

The given compound has the following structure:

COOH-CH2-C-O-O-CH3

This compound contains a carboxylic acid group (-COOH), an alkyl group (-CH2-), a carbonyl group (-C=O), an ether group (-O-O-), and a methyl group (-CH3). To determine the IUPAC name, we need to analyze the structure and identify the parent compound, substituents, and functional groups.

Identifying the Parent Compound

The parent compound is the largest continuous chain of carbon atoms in the molecule. In this case, the parent compound is a 4-carbon chain (butane).

Identifying Substituents and Functional Groups

The substituents and functional groups in the compound are:

Carboxylic acid group (-COOH): This is a functional group that is attached to the parent compound.
Alkyl group (-CH2-): This is a substituent that is attached to the parent compound.
Carbonyl group (-C=O): This is a functional group that is attached to the parent compound.
Ether group (-O-O-): This is a functional group that is attached to the parent compound.
Methyl group (-CH3): This is a substituent that is attached to the parent compound.

Determining the IUPAC Name

To determine the IUPAC name, we need to follow the rules of nomenclature:

The parent compound is named first.
The substituents are named in alphabetical order.
The functional groups are named in alphabetical order.
The suffix of the parent compound is changed to indicate the presence of a functional group.

Applying these rules, the IUPAC name of the compound is:

Butane-2-methyl-4-oxo-2-ethoxyacetic acid

Breaking Down the IUPAC Name

Let's break down the IUPAC name to understand its components:

Butane: This is the parent compound, a 4-carbon chain.
-2-methyl: This is a substituent that is attached to the parent compound at the 2-position.
-4-oxo: This is a functional group that is attached to the parent compound at the 4-position.
-2-ethoxy: This is a functional group that is attached to the parent compound at the 2-position.
-acetic acid: This is a functional group that is attached to the parent compound.

Conclusion

In conclusion, the IUPAC name of the compound COOH-CH2-C-O-O-CH3 is Butane-2-methyl-4-oxo-2-ethoxyacetic acid. This name provides a unique identifier for the compound and provides information about its structure and composition.
