1. The Base Structure:
* Pentanoic acid: This tells us we have a 5-carbon chain (pent-) with a carboxylic acid (-anoic acid) functional group at one end.
2. The "oxo" Group:
* 3-oxo: This indicates a ketone group (C=O) located on the third carbon atom of the chain.
3. Putting it Together:
* 3-oxo pentanoic acid: The structure will be a 5-carbon chain with a carboxylic acid group at one end and a ketone group on the third carbon.

Key Points:
* Carboxylic acid (COOH): The functional group at the end of the chain.
* Ketone (C=O): The functional group on the third carbon.
* Numbering: We start numbering the carbons from the end with the carboxylic acid group.
