Verified step by step guidance
1
Identify the functional group characteristic of ketones, which is a carbonyl group (C=O) bonded to two carbon atoms.
Examine each compound name to determine the functional group present. For example, 'pentanal' contains the suffix '-al', indicating an aldehyde, not a ketone.
Consider '2-pentanol', which has the suffix '-ol', indicating an alcohol, not a ketone.
Look at 'pentanoic acid', which has the suffix '-oic acid', indicating a carboxylic acid, not a ketone.
Recognize that '2-pentanone' has the suffix '-one', which is characteristic of ketones, confirming it as the correct name for a ketone.
