Other Organic Compounds: Functional Groups & Polymers
Functional Groups • Functional group: An atom or group of atoms attached to mainly hydrocarbons • Responsible for the specific properties of an organic compound • Types of functional groups – see chart provided in class
Type of Organic Reactions • Substitution Reactions - one or more atoms replace another atom or group of atoms in a molecule methane chlorine chloromethane hydrogen chloride
Addition Reactions - an atom or molecule is added to an unsaturated molecule and increases the saturation of the molecule
Polymers • Polymers - large chainlike molecules made from many small molecules called monomers • Simplest polymer – polyethylene • Polyethylene results from addition polymerization.
Condensation Polymerization - two molecules (monomers) or parts of the same molecule combine • Addition of more monomers creates polymer chains • Asmall molecule (often water) is released for each addition of a monomer to the polymer chain • Nylon
Condensation of amino acids in protein formation • A polymer of amino acids (many condensed into a long chain) is referred to as a polypeptide
