To solve the problem of naming the given organic compounds, we need to identify each compound based on its structure and apply the rules of IUPAC (International Union of Pure and Applied Chemistry) nomenclature. Let's analyze each compound step by step.
---
1. Compound 1:
```
H
|
H — C — C — C — H
| |
H H
```
- This is a straight-chain alkane with 3 carbon atoms.
- The parent chain is propane.
- There are no substituents or branches.
Name: Propane
---
2. Compound 2:
```
H
|
H — C — C — C — H
| |
H CH₃
```
- This is a straight-chain alkane with 4 carbon atoms.
- The parent chain is butane.
- There is a methyl group (CH₃) attached to the second carbon atom.
Name: 2-Methylbutane
---
3. Compound 3:
```
H
|
H — C — C — C — C — H
| | |
H H H
```
- This is a straight-chain alkane with 5 carbon atoms.
- The parent chain is pentane.
- There are no substituents or branches.
Name: Pentane
---
4. Compound 4:
```
H
|
H — C — C — C — C — H
| | |
H CH₂OH H
```
- This is a straight-chain alcohol with 4 carbon atoms.
- The parent chain is butane.
- There is a hydroxyl group (OH) attached to the second carbon atom.
Name: 2-Butanol
---
5. Compound 5:
```
H
|
H₃C — C — C — C — C — H
| | | |
H H H H
```
- This is a straight-chain alkane with 6 carbon atoms.
- The parent chain is hexane.
- There is a methyl group (CH₃) attached to the third carbon atom.
Name: 3-Methylhexane
---
Final Answer:
1.
Propane
2.
2-Methylbutane
3.
Pentane
4.
2-Butanol
5.
3-Methylhexane
$$
\boxed{\text{Propane, 2-Methylbutane, Pentane, 2-Butanol, 3-Methylhexane}}
$$
