The book is presented and organized in a way to discourage students from rote learning. It covers all the topics in Organic Chemistry included in the sylabi of Indian universities for undergraduate courses. Special emphasis is given to the basic concepts viz. acids and bases, hybridization and resonance. Functional groups, which are extremely important for the understanding of Organic Chemisrty, have been dicussed along with the hydrocarbons and the organometallic compounds. Other important topics covered include sulfur compounds, oxidations and reductions. All the important topics are represented in a format which is ideal for learning and rapid revision.
