"WebJul 20, 2014 · Both aldehydes and ketones contain the carbonyl group, C=O, and are often called carbonyl compounds. An aldehyde is often written as RCHO. Remember that the H atom is bonded to the carbon atom, not the oxygen. • Likewise, a ketone is written as RCOR, or if both alkyl groups are the same, R2CO. " - Ir spectrum of aldehydes and ketones
