This position of the-carbonyl group (oxygen atom) attached to a carbon atom that is. the last carbon atom in a carbon-chain is important because it distinguishes ketones from a similar category of organic compounds, called aldehydes. (In contrast to ketones, aldehydes include a-carbonyl group attached to the end-carbon in a carbon-chain. ).
