What is the IUPAC Name for the Following Compound?

Chemistry is a fascinating subject that deals with the study of matter and its properties. Organic chemistry, a subfield of chemistry, focuses on the study of carbon-based compounds. In this article, we will discuss one of the fundamental concepts of organic chemistry – IUPAC naming, and provide the IUPAC name for a specific compound.

Introduction to IUPAC Naming

The International Union of Pure and Applied Chemistry (IUPAC) is a global organization responsible for standardizing the names of chemical compounds. IUPAC names are systematic and unambiguous, providing a universal language for chemists to communicate about chemicals.

IUPAC naming is based on a set of rules that guide the naming process of organic compounds. The rules consider the type and number of atoms What is the IUPAC Name for the Following Compound present in the molecule, the functional groups attached to it, and the arrangement of those atoms and functional groups.

The Compound in Question

Let us consider the following compound for which we need to determine the IUPAC name:

This compound has seven carbon atoms, nine hydrogen atoms, and one oxygen atom. It also has a functional group – a ketone (C=O) – attached to one of the carbon atoms.

Steps to Determine IUPAC Name

To determine the IUPAC name of this compound, we need to follow a set of steps as outlined by the IUPAC rules:

Step 1: Identify the Longest Carbon Chain

The first step is to identify the longest continuous chain of carbon atoms in the molecule. In this case, the longest chain contains seven carbon atoms.

Step 2: Identify the Functional Group

Next, we need to identify the functional group present in the molecule. In this case, we have a ketone functional group attached to the second carbon atom.

Step 3: Number the Chain

We need to number the chain in a way that the functional group gets the lowest possible number. In this case, we can number the chain from left to right, so that the ketone gets the number 2.

Step 4: Name the Chain

We name the carbon chain using the prefix corresponding to the number of carbon atoms in the chain. In this case, the prefix is hept- for seven carbon atoms.

Step 5: Name the Functional Group

We name the functional group by replacing the -e suffix of the parent alkane with the suffix -one. In this case, the ketone functional group is named as heptan-2-one.

Step 6: Combine the Names

Finally, we combine the names of the chain and the functional group, and arrange them in alphabetical order. The IUPAC name for the given compound is 2-heptanone.


IUPAC naming provides a systematic and unambiguous way to name chemical compounds. By following a set of rules, we can determine the IUPAC name of any given organic compound. In the case of the compound we considered in this article, the IUPAC name is 2-heptanone.


  1. What is IUPAC naming? IUPAC naming is a set of rules developed by the International Union of Pure and Applied Chemistry (IUPAC) to provide a universal language for chemists to communicate about chemical compounds.
  2. What are functional groups? Functional groups are specific arrangements of atoms in a molecule that determine its chemical behavior and properties.
  3. What is a ketone functional group? A ketone functional group is a carbon-oxygen double bond (C=O) attached to a carbon atom in a carbon chain.
