WebAldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone.

They are formed when an alcohol oxygen atom adds to the carbonyl carbon of an aldehyde or a ketone. This happens … WebIf you use water, you will get a 1,1-diol, which is too unstable to be isolated, because the equilibrium shifts back to starting materials. RCHO + H₂O ⇌ RCH (OH)₂. Most aldehydes form equally unstable hemiacetals. RCHO + R'OH ⇌ RCH (OH)OR'. The most common exceptions are mono- and disaccharides (sugars).
