Here's the IUPAC name for the given structure:

Identify the highest priority functional group and the parent chain.
The molecule contains a carboxylic acid group ( $\text{-COOH}$ ) and a carbon-carbon double bond ( $\text{C}=\text{C}$ ). The carboxylic acid group has higher priority, so its carbon is designated as C1. The parent chain must include both the carboxylic acid and the double bond.
Determine the longest carbon chain and number it.
Starting from the carboxylic acid carbon (C1) and including the double bond, the longest continuous carbon chain is 7 carbons long.
$\text{C1}(\text{O})\text{OH} - \text{C2}(\text{CH}_3)=\text{C3}\text{H}_2 - \text{C4}\text{H}(\text{CH}_2\text{CH}_3) - \text{C5}\text{H}(\text{CH}(\text{CH}_3)_2) - \text{C6}\text{H}_2 - \text{C7}\text{H}_3$
The double bond is between C2 and C3. Therefore, the parent name is hept-2-enoic acid.
Identify and name the substituents.
- At C2: a methyl group ( $\text{CH}_3$ )
- At C4: an ethyl group ( $\text{CH}_2\text{CH}_3$ )
- At C5: an isopropyl group ( $\text{CH}(\text{CH}_3)_2$ )
Assemble the name in alphabetical order.
Alphabetical order of substituents is ethyl, isopropyl, methyl.

Combining these parts, the IUPAC name is:
$\text{4-ethyl-5-isopropyl-2-methylhept-2-enoic acid}$
