Compare the potential energy of `CH_(3) - CH_(3) , CH_(2) = CH_(2) CH -= CH`

Explanation

To compare the potential energy of ethane (CH₃-CH₃), ethylene (CH₂=CH₂), and acetylene (C≡CH), we can analyze the type of bonds present in each molecule and their corresponding energy levels.

### Step-by-Step Solution:

1. **Identify the Types of Bonds**:
- Ethane (CH₃-CH₃) has single bonds (C-C and C-H).
- Ethylene (CH₂=CH₂) has a double bond (C=C) and single bonds (C-H).
- Acetylene (C≡CH) has a triple bond (C≡C) and single bonds (C-H).
