Role of Functional Groups
Functional groups distinguish a molecule by determining its reactivity and how it interacts with other molecules. A functional group gives an organic substance a unique property that it would not have otherwise. A molecule’s functional groups determine the following:
Alkenes and Alkynes
Alkenes are unsaturated hydrocarbons with one or more double bonds between adjacent carbon atoms. The general molecular formula for the homologous series of alkenes is CnH2n, where n is the number of carbon atoms in one molecule. The general structure of an alkene is as follows:
Benzene
Benzene, having the molecular formula C 6 H 6, is a type of organic chemical compound. The benzene molecule is made up of three C=C double bonds that alternate with single bonds in a planar ring, each with one hydrogen atom linked to it.
Alcohol
Alcohol is a type of chemical substance with one or more hydroxyl groups. A hydroxyl group is made up of -OH. A carbon is single-bonded to a -OH group in the alcohol functional group. The general molecular formula for the homologous series of alkynes is CnH2n+1OH, where n is the number of carbon atoms in one molecule.
Ether
Ethers are a class of functional group chemical compounds that contain an ether group, which is an oxygen atom linked to two alkyl or aryl groups. They are represented by the generic formula R-O-R′, where R and R′ indicate alkyl or aryl groups.
Amine
Amine is an organic derivative of ammonia (NH 3 ). When the hydrogen atom (s) in NH 3 are replaced by R groups, amine is formed. Nitrogen atoms with single bonds to hydrogen and carbon describe amines.
Aldehydes
Aldehydes are carbonyl compounds with a hydrogen and an alkyl (or aromatic) group attached to them. Aldehyde can only exist at the end of a structure since H must be attached on one side of the C=O group. The generic formula RCHO is used to express them.
