Propionaldehyde, "CH"_3"CH"_2"CHO" With a "C=C" double bond and an "OH" group 3. If neither is hydrogen, the compound is a ketone.The IUPAC system of nomenclature assigns a characteristic suffix to these classes, al to aldehydes and one to ketones. Acetone is used as a solvent for various substances due to its ability to mix with most organic solvents and water. Because hexane has only C-H and C-C bonds (and no functional groups), this spectrum can help orient you to the important regions in an IR spectrum. Here, R and R’ denotes substituents of carbon. Compare it with the C=C in the previous case which are weaker and sharper. Acetone has a carbonyl group, where carbon and oxygen are bonded to each other with a double bond and is known as the simplest ketone. However, if the substituents in neither of the 2 remaining bonds are hydrogen, then the organic compound is a ketone. The chain isomerism arises due to different arrangements of carbon atoms leading to linear and branched chains. ethanal. The most important ketone is acetone, a liquid with a sweetish odor. Finally, the ether functional group is an O atom that is bonded to two organic groups: R—O—R′ The two R groups may be the same or different.
