Give IUPAC name for each of the following
`CH_(3)CH_(2)CH=CHCOOH`

Explanation

To determine the IUPAC name for the compound CH₃CH₂CH=CHCOOH, we will follow these steps:

### Step 1: Identify the longest carbon chain
The first step in naming an organic compound is to identify the longest continuous carbon chain. In this case, the longest chain consists of five carbon atoms (C1 to C5).

### Step 2: Identify functional groups
Next, we identify the functional groups present in the compound. Here, we have a carboxylic acid group (-COOH) at one end of the chain, which is a priority functional group. We also have a double bond (C=C) between the third and fourth carbon atoms.
