"A Proposal for the Expansion in Space of the Structural Formulas Used in Chemistry With Related Remarks on the Relation Between Optical Activity and the Chemical Structure of Organic Compounds" is an important work in the field of chemistry written by Jacobus Heinrich van 't Hoff. The book considers not only the expansion of structural formulas in three-dimensional space, but also the establishment of a relationship between the optical activity of compounds and their chemical structure. The author investigates such aspects in a number of organic compounds, which opens up new opportunities for understanding structural chemistry and the relationship between the structure of substances and their characteristics. This book has become a valuable source of knowledge for scientists and researchers in the field of chemistry."
