2-MethylPentane is unsaturated hydrocarbon. True/False

Explanation

To determine whether 2-methylpentane is an unsaturated hydrocarbon, we need to analyze its structure and bonding.

### Step-by-Step Solution:

1. **Understanding Hydrocarbons**:
- Hydrocarbons are organic compounds composed solely of carbon (C) and hydrogen (H) atoms.
- They can be classified into two main categories: saturated and unsaturated hydrocarbons.

2. **Defining Saturated and Unsaturated Hydrocarbons**:
- **Saturated Hydrocarbons**: These contain only single carbon-carbon (C-C) bonds. They are alkanes and have the general formula CnH2n+2.
- **Unsaturated Hydrocarbons**: These contain at least one double (C=C) or triple (C≡C) bond. They include alkenes (with double bonds) and alkynes (with triple bonds).

3. **Analyzing 2-Methylpentane**:
- The name "2-methylpentane" indicates that it is a branched alkane with a five-carbon chain (pentane) and a methyl group (−CH3) attached to the second carbon.
- The structure can be represented as follows:
```
CH3
|
CH3-CH-CH2-CH3
|
CH2
```
- In this structure, all carbon-carbon bonds are single bonds.

4. **Counting Carbon Atoms and Bonds**:
- Count the carbon atoms: 5 (from the pentane chain) + 1 (from the methyl group) = 6 carbon atoms.
- Check the types of bonds: All C-C bonds are single bonds.

5. **Conclusion**:
- Since 2-methylpentane contains only single bonds and fits the formula for saturated hydrocarbons (C6H14), it is classified as a saturated hydrocarbon.
- Therefore, the statement "2-methylpentane is an unsaturated hydrocarbon" is **False**.

### Final Answer:
**False**
