The book is primarily intended for the students pursuing an honours degree in chemistry. The chapters have been designed to enable the beginners to delve into the subject gradually right from the elementary aspects of organic chemistry, such as properties of molecules and nomenclature, to discussions on organic compounds in the traditional way, that is, beginning with the hydrocarbons and ending up with carboxylic acids and their derivatives with due emphasis on both aliphatic and aromatic compounds. This has been followed by heterocyclic compounds. Chapters on organic reaction mechanism and stereochemistry have been dealt with extra care to enable beginners to master organic chemistry to the core. Natural products, an important part of organic chemistry, have been dealt with due care avoiding too much detail. Each chapter has been supplemented with well chosen worked-out problems to help the students build a strong foundation in the subject.
