5. Trends in technology of oxygen containing hydrocarbons: aldehydes, ketones, ethers
Abstract
The structural element of many organic compounds in which the carbon atom combines with the oxygen atom in a double bond is called the carbonyl group. Both atoms forming such a double bond are characterized by hybridization of the sp2 type. Spatially, these two atoms and two other atoms directly related to the carbon atom lie in the same plane. One of the carbon-oxygen bonds is of σ type, formed by two overlapping sp2 orbital bonds, while the other is of π type, realized through the commonalization of non-hybridized electrons from orbital π. The carbonyl group “-C=O” is a common element in the structure of aldehydes and ketones and to a large extent determines their chemical properties. Aldehydes are organic compounds in which the carbonyl group is connected by one single bond to the hydrogen atom and the other to the rest of the hydrocarbon molecule. In aldehydes, the C=O group occurs at the end of the carbon chain; it is connected with a single C-C bond; the fourth bond is saturated with hydrogen atom. Ketones are organic compounds containing a carbonyl group which is combined with two hydrocarbon groups. In ketones, the C=O group occurs within the carbon chain of molecules; the carbon atom of the carbonyl group is secondary. Ethers are organic compounds in which C-O-C bonds are present, where none of the carbon atoms is bound to more than one oxygen atom.
