Give IUPAC name for each of the following
`{:(CH_(2)=C-CH_(2)CH_(3)),(" |"),(" "HC-CH_(3)),(" |"),(" "CH_(3)):}`

Explanation

To determine the IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
The first step in naming the compound is to identify the longest continuous chain of carbon atoms. In the given structure, we can see two possible chains:

1. CH2=CH-CH2-CH3 (4 carbons)
2. CH2-CH-CH3 (with a methyl group on the second carbon)
