Give structure formula of Hexana-2,5-dione.

Explanation

To derive the structural formula of Hexane-2,5-dione, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Carbon Chain**:
- The name "hexane" indicates that the compound has a straight-chain of 6 carbon atoms.

2. **Draw the Carbon Backbone**:
- Start by sketching a straight chain of 6 carbon atoms:
```
C1 - C2 - C3 - C4 - C5 - C6
```

3. **Locate the Ketone Groups**:
- The "2,5-dione" part of the name indicates that there are two ketone groups (C=O) located at the 2nd and 5th carbon atoms.

4. **Add the Ketone Groups**:
- Place a double bond to oxygen (C=O) at the 2nd and 5th carbon:
```
C1 - C2(=O) - C3 - C4 - C5(=O) - C6
```

5. **Add Hydrogen Atoms**:
- Now, we need to add hydrogen atoms to each carbon to satisfy the tetravalency of carbon:
- C1 will have 3 hydrogens (CH3)
- C2 will have 1 hydrogen (since it is bonded to one ketone and one carbon)
- C3 will have 2 hydrogens
- C4 will have 2 hydrogens
- C5 will have 1 hydrogen (similar to C2)
- C6 will have 3 hydrogens (CH3)

6. **Write the Complete Structural Formula**:
- Now, we can write the complete structural formula:
```
CH3 - C(=O) - CH2 - CH2 - C(=O) - CH3
```

### Final Structural Formula:
- The final structural formula of Hexane-2,5-dione is:
```
CH3 - C(=O) - CH2 - CH2 - C(=O) - CH3
```
