These structures can be found in many aromatic compounds contributing to smell and taste. In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound. The five remaining functional groups all contain a carbon/oxygen double bond, which is called a carbonyl. As stated previously, atoms of carbon can form four covalent bonds when incorporated into organic molecules. The group reacts in a typical way, generally independent of the rest of the moleculeindependent of the rest of the molecule For example, the double bonds in simple and complex alkenes react with bromine in the same way (See Figure 3 1)(See Figure 3.1) Types of Functional Groups: Multiple Carbon–Carbdbon Bonds Functional group: group of atoms with characteristic chemical behavior Reactions of organic molecules are governed by their functional groups, regardless of size and complexity of the molecule. Alkene: contains C=C double bond Alkyne: contains C ≡C triple bond Arene: contains a benzene (or other aromatic) ring Many functional groups have an There are a number of functional groups that contain a carbon-oxygen double bond, which is commonly referred to as a carbonyl.
