Alkenes II. Reactions of the
Carbon - Carbon Double Bond
Electrophilic and Free-Radical Addition


6.1 The functional group
The characteristic feature of the alkene structure is the carbon-carbon double
bond.
The characteristic reactions of an alkene are those that take place at the
double bond.
The atom or group of atoms that defines the structure of a particular
family of organic compounds and, at the same time, determines their properties is
called the functional group.
In alkyl halides the functional group is the halogen atom, and in alcohols the OH group; in alkcnes it is the carbon- carbon double bond. We must not forget that an alkyl halide, alcohol, or alkene has alkyl groups attached to these functional groups; under the proper conditions, the alkyl portions of these molecules undergo
the reactions typical of alkanes.
However, the reactions that are characteristic of
each of these compounds are those that occur at the halogen atom or the hydroxyl group or the
carbon-carbon double bond.
