First slide, at the bottom is a polymer change of poyl vinylidene chloride which can be viewed (along with PVC as an alkyl chloride)
Some introduction to alkyl halides, it is important to note that while alkyl halides are often thought of as man made there are plenty of examples from nature.
SN2 chemistry appears all over the organic chemistry. Also by understanding the SN2 reaction it will help you understand a lot of other reactions
What is a nucleophile, this is something important for you to learn. Nucleophiles will appear in many reactions. Also by understanding nucleophiles you will understand electrophiles.
Leaving groups are important, be careful of both thermodynamic and kinetic effects
This mechanism is important, by understanding the SN2 reaction you will help yourself with many other reactions in organic chemistry
Key thing to remember is backside attack
Get out the pop corn and sit back and watch the film.
Different alkyl groups, look at the different sizes of them.
A problem for students to do. By the way thiophenol smells just like burning car tyre rubber.
Some problems for you to do, try to predict what will happen in each case.
A problem for the students to do at home.
Part of the synthesis of a drug, note that the ester group gives special reactivity to the alkyl bromide. Note the details of the early version of tear gas which the paris police used.
Something for next time
