More complicated chemical molecules may contain more than one functional group within their structure, which can sometimes affect the chemical reactions they undergo. The names of organic molecules are systematic references to the functional groups within the molecule, and can thus be used to identify these. functional group in chemistry is the part of the molecule that gives it its particular reactivity; simple molecules that contain the same functional group in their structure can be expected to react in similar ways.
