Sec 1 Classification Reactions can be classified as carbon-carbon bond formations o construct complex molecules from simple starting materials In general,these reactions are the most difficult and temperamental to carry out. reactions are so important that they are named after the scientists who developed them (e.g.Grignard and Aldol reactions) Also classified according to the process or mechnism
SEC 2 Mechanism A mechanism is the 'story'of how a reaction takes place. A mechanism describes how a reaction takes place by showing what is happening to valence electrons during the formation and breaking of bonds
