WebA brief introduction to organic chemistry. Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. WebCarbonyl function. The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides. Ester. Esters have a pair of alkyl or aromatic groups attached to a carbonyl + linking oxygen function.
