Tackle the 2011 organic paper then check with assessment schedule . Make sure that you see me about any problems with the paper. Make an appointment for extra help if required.

Organic chemistry is the chemistry of molecules that are largely composed of carbon.
Many organic molecules have the same molecular formula but different structural formulae
Organic molecules are named with reference to the carbon skeleton and following rules
Functional groups attached to the carbon skeleton confer specific chemical properties to the molecule. ( -OH attached to the chain turns the molecule into an alcohol)
Adrenaline is an example of a molecule where changing functional groups attached to a 3 carbon chain can have a dramatic effect on the chemistry of a molecule.
If you have joined my class from Aaron’s group you should have a look at the video.
Finally look at this beautiful wee dancing molecule….
- Name the molecule
- What is its molecular formula
- Name all possible structural isomers and draw full structural formulae
If you take the time to do this you will have no difficulty naming molecules with functional groups attached….but first watch this wee molecule dance.
