3.3.1.3 Isomerism

Content	Opportunities for skills development
$Structural isomerism. Stereoisomerism. E - Z isomerism is a form of stereoisomerism and occurs as a result of restricted rotation about the planar carbon-carbon double bond. Cahn-Ingold-Prelog (CIP) priority rules. Students should be able to: define the term structural isomer draw the structures of chain, position and functional group isomers define the term stereoisomer draw the structural formulas of E and Z isomers apply the CIP priority rules to E and Z isomers.$	$MS 4.2 Students could be given the structure of one isomer and asked to draw further isomers. Various representations could be used to give the opportunity to identify those that are isomeric. MS 4.1, 4.2 and 4.3 Students understand the origin of E - Z isomerism. Students draw different forms of isomers.$
