How many covalent bonds are present in butane?

Explanation

To determine the number of covalent bonds present in butane, we can follow these steps:

### Step 1: Understand the Structure of Butane
Butane (C₄H₁₀) consists of four carbon atoms and ten hydrogen atoms. It has a straight-chain structure.

### Step 2: Draw the Lewis Structure
1. **Carbon Atoms**: Each carbon atom can form four bonds because it has four valence electrons.
2. **Hydrogen Atoms**: Each hydrogen atom can form one bond because it has one valence electron.
