This textbook has been revised to cover the latest syllabuses from all examination boards, the BTEC National Certificate and some chemistry diplomas. Knowledge of topics at GCSE level is not assumed. Many new sections relate chemistry to social, economic, environmental and technological contexts. Tables and reaction schemes summarize much of the detailed organic and inorganic chemistry, and plenty of test questions are provided. Checkpoints at intervals throughout the book allow students to assess their understanding at each stage. Margin summaries are included and diagrams are fully integrated with descriptive material.
