Functional Groups
is a part of a larger molecule, composed of
an atom or group of atoms that have
characteristic behaviour.
The basis of organic chemistry is the structural
theory.


Thus, all organic compounds can be separated into a
number of families (functionalities) on the basis of
structure.
The chemistry of every organic molecule, regardless
of the size and complexity is determined by the
functional groups it contains.
