Write the IUPAC name of `CH_(3)CH=CH-underset(Br)underset(|)overset(CH_(3))overset(|)C—CH_(3)`.

Explanation

To derive the IUPAC name of the compound `CH₃CH=CH(Br)C(CH₃)C(CH₃)`, we will follow these steps:

### Step 1: Identify the longest carbon chain
The first step is to identify the longest continuous carbon chain in the compound. In this case, we can see that the longest chain consists of 5 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 (alkene) to give it the lowest possible number.
