Nucleophilic Substitution - SN1

One of a series of videos extracted from a Flash project (unfinished) that will eventually cover all the Mechanisms met in the Advanced Chemistry course as taught in Scottish Schools. http://new.chemistry-teaching-resources.com/Mechanisms.html. This video is the second of 3 looking at Nucleophilic Substitution. It considers the SN1 mechanism in which the halogen leaves first to form a carbocation intermediate - First Order Kinetics.
