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.
In organic chemistry, functional groups are specific groups of atoms within molecules arranged in a specific manner. The following tables list common functional groups arranged by heteroatom. The location of the carbonyl group in the molecule is identified by numbering the longest chain of carbons so that the carbonyl group has the lowest number possible. is 2-pentanone Aldehydes When one of the groups attached to the carbonyl group is a hydrogen instead of a carbon, the compound is called an aldehyde. Aldehydes are given an -al ending.

The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds.

The transformation is efficient (equimolar amts. of the starting materials are used), generally high-yielding (all but one between 55 and 88% yield), highly functional-group-tolerant [OH, NHBoc, NHCbz, Bpin, C(O)Me, CO2Et, and CN are all tolerated], and easy to perform (uses only benchtop-stable reagents, tolerates small amts. of water and
Bromine reacts with 2-butene to form 2,3-dibromobutane. It also reacts with 3-methyl-2-pentene to form 2,3-dibromopentane.
nucleophilic α-C of an enolate ion adds to C of C=O groups in various carbonyl compounds. Reactions (c) are increase the number of functional groups in a molecule by subsequently replacing the α-C-X R-C(=O)-R' + -:C-CO2Et.
