Introduction to the examination and changes to the syllabus Advice on how to revise for and approach examinations Answers to end-of-chapter questions Recommended resources CD1 CD4 CD10 CD76 How to use this book Each chapter begins with a short list of the facts and concepts that are explained in it There is a short context at the beginning of each chapter, containing an example of how the material covered in the chapter relates to the ‘real world’ This book does not contain detailed instructions for doing particular experiments, but you will find background information about the practical work you need to in these boxes There are also two chapters, P1 and P2, which provide detailed information about the practical skills you need to develop during the course vi Important equations and other facts are shown in highlight boxes Questions throughout the text give you a chance to check that you have understood the topic you have just read about You can find the answers to these questions on the CD-ROM The text and illustrations describe and explain all of the facts and concepts that you need to know The chapters, and often the content within them as well, are arranged in the same sequence as in your syllabus How to use this book Wherever you need to know how to use a formula to carry out a calculation, there are worked example boses to show you how to this Definitions that are required by the syllabus are shown in highlight boxes Key words are highlighted in the text when they are first introduced You will also find definitions of these words in the Glossary vii There is a summary of key points at the end of each chapter You might find this helpful when you are revising Questions at the end of each chapter are more demanding exam-style questions, some of which may require use of knowledge from previous chapters Answers to these questions can be found on the CD-ROM Cambridge International AS Level Chemistry Recommended resources Chapter 18: Carbonyl compounds
