Document Summary
Polymerization: addition of an alkene to an alkene polymer- a macromolecule of repeating structural units monomer- the small molecule that reacts to form the repeating unit in a polymer. With high temperature and pressure. synthetic polymers are used to replace diseased veins and arteries. Sometimes we draw one of the resonance structures. Sometimes we try to represent the system. aromatics have at least one aromatic ring i(cid:374)di(cid:272)ated (cid:271)(cid:455) (cid:862)-benz-(cid:863) or (cid:862)-phen- in iupac name.

Common nomenclature is regularly used when two substituents are present on benzene. Dr. kehres" rules for (cid:374)a(cid:373)i(cid:374)g aro(cid:373)ati(cid:272) (cid:272)o(cid:373)pou(cid:374)ds: if present, use common name for toluene, phenol, aniline, if benzene ring contains two substituents, use o-, m-, p, if more than two substituents, use numbering system. Heterocyclic aromatic compounds have a system that includes n or o.
