Write structures and IUPAC names of different structural isomers of alkenes corresponding to ` C_(5)H_(10)`.

Explanation

To find the structural isomers of alkenes corresponding to the molecular formula C5H10, we need to identify different arrangements of carbon atoms and the placement of the double bond. Here are the steps to derive the structures and IUPAC names:

### Step 1: Identify the Base Structure
The molecular formula C5H10 indicates that we have 5 carbon atoms and a degree of unsaturation (due to the presence of a double bond). The base structure can be a straight chain or branched.

### Step 2: Draw the Straight Chain Isomers
1. **1-Pentene**:
- Structure: CH2=CH-CH2-CH2-CH3
