Review: Functional Groups, Organic Families, Properties, and Reactions
Functional Groups
Functional groups give defining properties to the different families of organic compounds. Many of the
functional groups are listed in the Summary of p.201 of your text and can be simply described by how
they look, e.g. C = C bond, or a C - O bond, or a C - Cl bond. Other functional groups have a specific
name for the atoms and their bonding arrangement. Give the specialized name for each of the
following functional groups:
