The book deals with the recognition of asymmetry in molecules of practical utility in revolutionary chemistry. The book consists of six chapters quoted with references. The first chapter includes the introductory evolution, drug discovery from so many years ago. Why the optically pure fragrances have much pleasant odour also described. The other chapters designed taking specific class of compounds. Second chapter involves so many features about the chiral drugs. Third chapter reveals Chiral flavor, fragrances, food & natural oil in market.Fourth chapter tells about the chiral agrochemicals ,herbicides and fungicides according to market survey.Fifth chapter is about a brief of chiral natural & synthetic Polymer & how stereochemistry designed in polymers. Sixth chapter describe a short story of optically active Metal complexes and their application.Perhaps this book shows the introductory part of almost type of chiral products. The portion of definitions & abbreviation are kept at the end of book. This will help to know some technical or important keywords.
