A hydrocarbon involving only single covalent bonds is called_____ (unsaturated/saturated.)

Explanation

To solve the question, "A hydrocarbon involving only single covalent bonds is called_____ (unsaturated/saturated)," we need to understand the definitions of saturated and unsaturated hydrocarbons.

### Step-by-Step Solution:

1. **Understand Hydrocarbons**: Hydrocarbons are organic compounds that consist entirely of hydrogen and carbon atoms. They can be classified based on the types of bonds between the carbon atoms.

2. **Identify Types of Bonds**:
- **Single Covalent Bonds**: These are bonds where two atoms share one pair of electrons. In hydrocarbons, this means that each carbon atom is connected to other carbon atoms (or hydrogen atoms) through single bonds.
