In this module we will begin to examine some of the properties of organic molecules that are important in determining their reactivity - particularly the acidity of H-atoms in those molecules.

'Nucleophiles' commonly have an electron lone pair produced by loss of a proton from a molecule and can act as reagents where the lone pair forms a bond to a suitable atom in another molecule. We will examine the characterisitcs of 'nucleophiles' and 'electrophiles' and ways of representing the process of reaction between them.
