Find the total structural isomers of `C_(4) H_(6)`

Explanation

To find the total structural isomers of the compound with the formula \( C_4H_6 \), we can follow these steps:

### Step 1: Determine the Degree of Unsaturation (DU)
The degree of unsaturation can be calculated using the formula:

\[ DU = \frac{(2C + 2 - H)}{2} \]
