Nomenclature: Ketones and Aldehydes

Ketones (R-CO-R) take the suffix "-one" with a position number: \(CH_3CH_2CH_2COCH_3\) is pentan-2-one. Aldehydes (R-CO-H) take the suffix "-al": \(CH_3CH_2CH_2COH\) is butanal. If a higher precedence suffix is in use, the prefix "oxo-" is used: \(CH_3CH_2CH_2COCH_2CHO\) is 3-oxohexanal.

Complete the names in the figure below:
