The textbook of organic chemistry is compiled in the main part by Y. L. Goldfarb and L. M. Smorgonsky and in terms of determining molecular weights - by V. N. Verkhovsky, who also owns the general edition of the book. Due to the great importance of the integrity of the presentation and construction of theoretical material in organic chemistry, the authors in this book deviated from the order of distribution of material adopted in Inorganic chemistry. Practical works here are given at the end of the book, not included in the text.
