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 catalytic system nickel/dcype is essential to achieve this fully reversible transformation in good to excellent yields. Furthermore, the cyanide- and thiol-free reaction shows high functional group tolerance and great efficiency for the late-stage derivatization of commercial molecules.

Up The Carbonyl Group. You may have noticed that several functional groups contain a C=O unit. This is called a carbonyl group.The substituents attached to the carbon atom of the carbonyl group determine whether a functional group is an aldehyde, ketone, carboxylic acid, ester, or amide. spectrum of pathogens. Write the name of each of the circled functional groups on the lines provided below. Answers: 1 ester or carboxylic ester, 2 amine, 3 aldehyde, 4 ether, 5 alcohol 13.
