Write the names of the following compounds :
`H-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-underset(H)underset(|)overset(H)overset(|)(C)-overset(O)overset(||)(C)-H`

Explanation

To name the given compound, we will follow the systematic approach for naming organic compounds. Here’s a step-by-step solution:

### Step 1: Identify the Parent Chain
First, we need to identify the longest continuous chain of carbon atoms in the compound. In the given structure, we can see that there are 5 carbon atoms in a straight chain.

### Step 2: Determine the Functional Group
Next, we need to identify any functional groups present in the compound. The structure shows a carbonyl group (C=O), which indicates that this is an aldehyde since it is at the end of the carbon chain.
