Question

what is the IUPAC name

**Title:** Naming Organic Compounds: IUPAC Nomenclature

**Content:**

**Objective:**
Write the correct IUPAC name for the following molecule.

**Molecular Structure Overview:**

The molecule consists of a carbon chain with various functional groups and branches, described as follows:

1. **Main Chain:** Identify the longest continuous carbon chain. In this structure, it is a six-carbon chain (hexane).

2. **Functional Groups:**
- There is a hydroxyl group (-OH) attached to the first carbon.

3. **Branches/Substituents:**
- A methyl group (CH₃) is attached to the third carbon.
- Another methyl group is attached to the fourth carbon.

**Naming Steps:**

1. **Determine the Longest Chain:** The main chain is a six-carbon chain, so the base name is "hexane."

2. **Identify and Number the Carbon Atoms:** Number the carbon atoms from the end nearest the hydroxyl group to ensure the lowest numbers for substituents. This gives priority to the functional group for naming.

3. **Name the Substituents:** Identify and name the substituents:
- Methyl groups on the third and fourth carbons.

4. **Combining the Names:**
- The IUPAC name is derived by combining the names of the substituents in alphabetical order with the position number, followed by the main chain name, and indicating the presence of the hydroxyl group.
- The correct IUPAC name is: **4,5-dimethylhexan-1-ol**.

**Conclusion:**

Understanding the structure and systematically identifying each component according to the IUPAC nomenclature rules allows for the accurate naming of complex organic molecules.

Expert Solution

Step 1: Nomenclature rules

The IUPAC name of the compound is given by using the rules of IUPAC nomenclature.

The rules can be summarised as-

Select the longest carbon-containing chain, known as the parent chain containing functional group.
The general formula to name the compound is given as prefix + root word + suffix.
Number the parent chain in such a way that the functional group attached gets the least possible number.
The name and number of substituents are used as a prefix.
The root word represents the count of carbon atoms that constitute the longest continuous chain.
The suffix comprises a primary suffix and a secondary suffix. The primary suffix is the type of bond present in the compound (single, double, or triple) whereas the secondary suffix is any functional group.
