Write the IUPAC name of `CH_3 underset(CH_2) underset(|) CH-CO-underset(CH_3 ) underset(|) CH -CH_3`

Explanation

To find the IUPAC name of the compound `CH_3(CH_2) | CH-CO(CH_3) | CH-CH_3`, we will follow these steps:

### Step 1: Identify the Longest Carbon Chain
First, we need to identify the longest continuous carbon chain in the compound. In this case, the longest chain consists of 5 carbon atoms.

### Step 2: Number the Carbon Chain
Next, we will number the carbon chain. We can choose to number it from either end, but we will choose the left side for this example. The numbering will be as follows:
1. CH3 (1)
