THE STRUCTURAL PROPERTIES AND SPATIAL ISOMETRIES

The structural theory was the first theory proposed order allowing organic compounds of natural origin that were isolated during the eighteenth and nineteenth centuries. Currently still appear new compounds but initial postulates of structural theory cannot be applied rigorously on these ones. However, the concept of structure in organic compounds has been maintained over the years: The structure of an organic compound is defined by its constitution and stereochemistry. IUPAC also states that the structure of an organic compound is established by its constitution and stereochemistry.
