F332 - Module 3(PR) Polymer Revolution


Recognise where E/Z isomerism occurs, explaining it in terms of lack of free rotation about C=C bonds when there are two different groups on each carbon;

Draw and interpret diagrams to represent E/Z isomers for alkenes which have the same groups on both sides of the double bond (E – opposite sides of bond; Z – same side of

In such molecules, describe ‘E’ as ‘trans’ and ‘Z’ as ‘cis’ and extend this cis-trans nomenclature to other, more complicated, alkenes (knowledge of Cahn–Ingold– Prelog priority rules will not be required);
