Question
**Task: Determine the IUPAC Name**

**Description:**

The image depicts a condensed structural formula, and the task is to provide its IUPAC name.

**Structure Explanation:**

The structure given is:

```
     CH3
      |
CH3—CH—CH—CH3
      |
     CH3
```

**Steps to Determine the IUPAC Name:**

1. **Identify the Longest Carbon Chain:**
   - The longest chain consists of three carbon atoms, making it a propane.

2. **Identify Substituents:**
   - There are two methyl (CH₃) groups attached to the middle carbon of the main chain.

3. **Number the Chain:**
   - Number the chain from the end nearest a substituent to give the lowest possible numbers to the substituents:
     - Carbon 1: CH₃
     - Carbon 2: CH(CH₃)₂
     - Carbon 3: CH₃

4. **Name the Structure:**
   - The IUPAC name is 2,2-dimethylpropane, indicating two methyl groups on the second carbon of the propane chain.

**Button Selection:**
- To construct the correct IUPAC name based on the provided options, select:
  - "2,2-"
  - "di"
  - "methyl"
  - "propane"

By using these steps, you will correctly identify the structure as 2,2-dimethylpropane.
