**IUPAC Naming of Organic Compounds**

This educational page explains the process of naming organic compounds using the IUPAC (International Union of Pure and Applied Chemistry) system. Below, we walk through the steps involved in determining the correct IUPAC name for the presented compound.

### Example Compound

Provide the correct IUPAC name for the compound shown here:

**Structure:**
```
   Br      Br
    |        |
CH3—CH—CH—CH3
```

### Naming the Compound

To form the IUPAC name for the given compound, follow these steps:

1. **Identify the Longest Carbon Chain:**
   - The presented structure shows a four-carbon chain, making the base name "butane."

2. **Number the Carbon Chain:**
   - Number the carbon atoms in the chain such that the substituted carbon atoms get the lowest possible numbers. In this case, numbering from left to right:
     ```
     1     2     3     4
     CH3—CH—CH—CH3
          |
          Br      Br
     ```

3. **Identify and Name Substituents:**
   - The substituents in this structure are bromine atoms (Br) attached to the second and third carbon atoms:
     - Position 2 has a bromine (2-bromo)
     - Position 3 also has a bromine (3-bromo)

4. **Combine the Substituent Names with the Base Name:**
   - List the substituents in alphabetical order or in numerical order by their positions along with the base name (butane). The prefixes (di-, tri-) are used for multiple identical substituents:
     - 2,3-dibromobutane

### Interactive Components

Below the compound structure, there are various options to help form the correct IUPAC name. These options include prefixes, suffixes, and different substituent names commonly used in organic chemistry:

- **Positional Indicators:** 2,4- 3- 1,3- 2,3- 2- 4-
- **Prefixes/Suffixes:** di sec- cyclo tert- iso tri
- **Base Names and Substituents:** prop bromo but meth chloro pent
- **Hydrocarbon Suffixes:** ene ane yne

These elements can be combined to form the name of a specific compound by choosing

### Naming Organic Compounds: IUPAC Naming Practice

#### Question:
**Provide the correct IUPAC name for the compound shown here.**

#### Diagram:
A chemical structure is depicted showing a hexagon representing a six-membered carbon ring (cyclohexane) with a chlorine (Cl) atom attached to one of the carbons.

#### Answer Options:
Below the diagram, various selectable segments are provided to construct the IUPAC name. These segments include:

- Numerical prefixes: `2-`, `6-`, `3-`, `5-`, `4-`, `1-`
- Multiplicative prefixes: `tri`, `di`
- Structural prefixes: `sec-`, `tert-`
- Cyclo prefix: `cyclo`
- Isomeric prefix: `iso`
- Substituent groups: `brom`, `chloro`, `bromo`, `chlor`
- Root names and suffixes: `hex`, `ane`, `yne`, `ene`

#### Instructions:
Using the provided segments, construct the correct IUPAC name for the given compound by selecting the appropriate segments and arranging them in the correct order.

#### Explanation:
The structure shows a cyclohexane ring with a single chlorine atom substituting one hydrogen atom. The chlorine is positioned in such a way that it will be given the lowest possible number on the ring for proper naming.

### Solution:
- Identify the main compound: cyclohexane
- Determine the position of the chlorine substituent: Since there is only one substituent, it will automatically be at position 1.

Therefore, combining these parts, the correct IUPAC name for the compound is:
**1-chlorocyclohexane**
