This unit will cover various aspects of Organic Chemistry. Particular emphasis will be placed on using deductive reasoning to predict the properties and behaviour of the different organic materials based on their electron distribution.
Many reactions are reversible. These reactions will reach a state of equilibrium when the rates of the forward and reverse reaction are equal. The position of equilibrium can be controlled by changing the conditions.
