C4H8 has 4 isomers.

Here's the step-by-step explanation:

1. Identify the type of hydrocarbon: C4H8 is an alkene, which means it contains a carbon-carbon double bond.

2. Draw the basic structure: The simplest structure you can draw is a four-carbon chain with the double bond at one end.

3. Move the double bond: For each subsequent isomer, move the double bond one position along the chain.

4. Change the shape of the chain: Once you've moved the double bond to every possible position on a straight chain, start creating branched chains.

5. Check for duplicates: Make sure none of your structures are the same as another but just drawn differently.

Following these steps, you will find that there are 4 isomers of C4H8: 1-butene, 2-butene, 2-methylpropene, and cyclobutane.
