Cyclic `C_(4)H_(7)OH` has five isomers. Write their structure and names.

Explanation

To determine the five isomers of cyclic compound \( C_4H_7OH \), we will analyze the structure and naming of each isomer step by step.

### Step 1: Determine the Degree of Unsaturation
The degree of unsaturation (DB) can be calculated using the formula:
\[ \text{DB} = \frac{C + 1 - H - N + X}{2} \]
Where:
