  1. Reactions of Benzene

  2. Benzene Structure Recap Objective To know about the structure of benzene Success criteria • Recall the structure of benzene • Describe the evidence for the structure of benzene • Explain the evidence for the structure of benzene • Name compounds containing benzene

  3. Evolution of scientific knowledge The history of the structure of benzene exemplifies how scientific knowledge evolves dynamically between different ideas as new data emerges. C6H6 Each successive model can be seen as a working hypothesis that best explains current observations, but which is only tentative in nature, as new information may require revision or even replacement of the current model.

  5. What are arenes? Arenes are aromatic hydrocarbons that contain one or more benzene rings. The name aromatic derives from the fact that many strong-smelling substances found in nature, such as plant fragrances, contain benzene rings. For example,vanillin(right) isthe fragrant compound found invanilla plants. However, more recently it has been found that the presence of a benzene ring has little to do with the smell of a substance. Many compounds containing benzene rings have no odour.

  6. Naming aromatic compounds Benzene derivatives are named in a similar fashion to other organic compounds, with benzene forming the main part of the name. The presence of other groups is denoted by the use of a prefix. methylbenzene chlorobenzene nitrobenzene

  7. Others are named as compounds with a phenyl group (C6H5) attached. Phenol Phenylamine
