Verified step by step guidance

Identify the parent chain: The name '2,4-dimethyl-3-pentanone' indicates that the parent chain is a pentanone, which means it is a five-carbon chain with a ketone group.

Locate the ketone group: The '3-pentanone' part of the name specifies that the ketone group (C=O) is on the third carbon of the chain.

Identify the substituents: The '2,4-dimethyl' part of the name indicates that there are methyl groups attached to the second and fourth carbons of the parent chain.

Analyze the structures: Look at each provided structure to determine which one has a five-carbon chain with a ketone group on the third carbon and methyl groups on the second and fourth carbons.

Select the correct structure: The correct structure will match the description of having a ketone on the third carbon and methyl groups on the second and fourth carbons of a five-carbon chain.
