Give two examples of: Unsaturated hydrocarbons involving C=C bond

Explanation

To answer the question about unsaturated hydrocarbons involving a carbon-carbon double bond, we can follow these steps:

### Step-by-Step Solution:

1. **Define Unsaturated Hydrocarbons**:
- Unsaturated hydrocarbons are organic compounds that contain at least one double bond (C=C) or triple bond (C≡C) between carbon atoms. They are called "unsaturated" because they can react with additional hydrogen atoms, leading to more saturated compounds.

2. **Identify the Type of Unsaturated Hydrocarbon**:
