Give the `IUPAC` name of the following compound.
`CH_(2) = CH - CH (CH_(3))_(2)`

Explanation

To determine the IUPAC name of the compound `CH₂=CH-CH(CH₃)₂`, we will follow these steps:

### Step 1: Identify the longest carbon chain
The first step is to identify the longest continuous carbon chain that contains the double bond. In this case, the longest chain consists of four carbon atoms.

### Step 2: Number the carbon chain
Next, we need to number the carbon chain. We will start numbering from the end closest to the double bond to give it the lowest possible number. The numbering will be as follows:
1. CH₂ (1)
