The present trend in competitive examinations is the stress on an objective rather than subjective treatment of the subject matter. Critical scrutiny of the question papers of previous years of various entrance tests reveals that a variety of questions such as very short answer type, short answer type, fill up the blanks, true and false, and multiple choice numerical type is usually asked. With these objectives in mind, the author has tried to present chemistry for competitions in two volumes covering the whole of syllabus of nearly all the competitions. The complete subject matter has been arranged in a systematic manner in each volume. Every topic has been dealt with precisely and to the point in simple and understandable language. Things have been explained with proper reasonings wherever possible. A good number of illustrations and solved problems including numerical problems have been provided to understand the theoretical aspects. In volume I, every chapter has been provided with a synopsis, i.e., a summary of the chapter for quick revision of principles and mathematical formulae at the time of examination. In volume II, several chapters have been supplemented with Supplementary Reading pertaining to the subject matter of higher standard on which questions are asked in competitions. In both volumes flow sheet diagrams have been given to simplify the extraction of various elements, and preparation of a number of compounds and their properties. At the end of each chapter, a good number of questions of various types have been given for self-assessment. It is our belief that students will be duly rewarded if they attempt these questions honestly and sincerely after learning the particular topic. Necessary hints have been given wherever it is felt necessary.
