An important feature of learning a subject is to be able to slove the problems that arise in that study. For a proper understanding of a scientific text and an appreciation for the formulas and the propositions exposed in it, it is necessary to solve the problems in the text by oneself. This book is written to help the students of chemistry in this task.The collection of chemistry problems from various sources and their solutions given here should be of great use to the final year secondary school and the pre-university students studying chemistry(A-level,Baccalaureate,CBSE etc.) Importantly,it can be fruitfully used by students appearing for competitive entrance examinations for the Engineeing and the Medical schools in the Indian subcontinent and the Gulf countries.
