This book entirely covers all the topics in form 2 chemistry of the new secondary school syllabus. The text is carefully structured with a lot of emphasis on consistency. It is written in a clear and straightforward language that the average secondary school student can easily understand. A lot of experiments have been included to enhance student participation in the learning process. The book is illustrated with very clear diagrams making it visually appealing. At the end of every chapter are well thought out examination-type revision questions.
