Write the systematic IUPAC names of the following compounds :
`CH_3 - CH= overset(CH_3) overset(|) C - CH_2 OH `

Explanation

To determine the systematic IUPAC name of the given compound, 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 the given structure, we can see that the longest chain consists of four carbon atoms.

### Step 2: Number the carbon chain
Next, we need to number the carbon chain. Since the compound contains an alcohol (–OH) functional group, we will start numbering from the end closest to the –OH group to give it the lowest possible number.
