Which functional group is characteristic of organic compounds classified as ketones?

💡 Solution & Explanation

Ketones contain a carbonyl group bonded to two carbon-containing hydrocarbon groups, represented generally as R-C-O-R. Hydroxyl groups characterize alcohols, carboxyl groups define carboxylic acids, and ester linkages define esters. Propanone, commonly known as acetone, is the simplest aliphatic ketone used widely as a solvent.
