Stereoisomers at AS level

This resource introduces E/Z (geometrical) isomers at AS level.
There is first a recap on prior knowledge in relation to naming and structural isomers formed by alkenes.
Students then work out why alkenes form stereoisomers by identifying restricted rotation about the double bond.
Then they work out the two criteria for alkenes to exist as stereoisomers along with some practice naming compounds.
There are then some examples of using the Cahn-Ingold Prelog method to identify isomers as E or Z. This is followed by practice,
Answers are given to all the questions throughout the lesson.
