Written for students taking either the University of Cambridge Advanced Level examinations or the International Baccalaureate examinations, this guidebook covers essential topics and concepts under both stipulated chemistry syllabi. The book is written in such a way as to guide the reader through the understanding and applications of essential chemical concepts using the problem solving approach. The authors have also retained the popular discourse feature from their previous two books — Understanding Advanced Physical Inorganic Chemistry and Understanding Advanced Organic and Analytical Chemistry — to help learners better understand and see for themselves how the concepts should be applied to solve problems. Based on the Socratic Method, questions are implanted throughout the book to help facilitate the reader's development in forming logical conclusions of concepts and the way they are being applied to explain the problems. In addition, the authors have also included important summaries and concept maps to help learners recall, remember, reinforce and apply the fundamental chemical concepts in a simple way.

Explanation: Let the bond energy of O–O bond in hydrogen peroxide be BE(O–O). Total energy absorbed during bond-breaking = 2 × BE(O-O). Total energy released during bond forming = 1 × 486 = 486 kJ mol-1. Hence, DH = 2 × BE(O-O) - 486 ...
Existing A-level or IB guidebooks generally introduce concepts in a matter-of-fact manner. This book adds a unique pedagogical edge which few can rival.

The ES students have little experience with inquiry labs or problem solving in this context and they struggle with these new skills and expectations. Most of these students are eventually successful at identifying their unknown solids, ...
Q: A: minimises inter-nuclei repulsion to a greater extent than in the case of the pi bond. Can there be two sigma bonds formed between the two atoms? Absolutely not. The formation of two sigma bonds will result in too much accumulation ...
bond, and (ii) the sigma bond in a C=C double bond is not of the same strength as that in a C–C single bond. In fact, the presence of an extra pair of pi electrons in the C=C double bond actually weakens the sigma bond in it due to an ...
