The total number of cyclic isomers possible for a hydrocarbon with the molecular formula `C_(4)H_(6)` is …..

Explanation

To determine the total number of cyclic isomers possible for a hydrocarbon with the molecular formula \( C_4H_6 \), we can follow these steps:

### Step 1: Identify the Structure
The molecular formula \( C_4H_6 \) suggests that the hydrocarbon can have multiple structural forms, including cyclic structures. The presence of fewer hydrogen atoms compared to saturated hydrocarbons indicates the possibility of double bonds or rings.

### Step 2: Draw Cyclic Structures
We can start drawing cyclic structures for \( C_4H_6 \). The following cyclic structures can be formed:
