THIS A DISTINCTION LEVEL ASSIGNMENT This assignment explores the structure, reactions, and industrial importance of aromatic compounds, focusing mainly on benzene and its derivatives. It explains how the delocalised π-electron system in benzene contributes to its stability, bond uniformity, and chemical behaviour, contrasting Kekulé’s structure with the modern delocalised model. The project discusses key reactions of benzene, including electrophilic substitution, sulfonation, Friedel–C...
