PHYSICAL CONSTANTS and STRUCTURAL FORMULAS of ORGANIC COMPOUNDS
CHEM203 Organic Chemistry I
Name__________ ____________
It is important to know the physical constants (such as melting point, mp; boiling point, bp; and density, d) and other information of the compounds being used
in an experiment for both stoichiometric calculations and for comparison of experimental data. Common references available to organic chemists include the
Aldrich Chemical Catalog or ACROS Organics Catalog. Also useful are the Dictionary of Organic Compounds, the CRC Handbook of Organic Compounds
and the Merck Index, as well as on-line resources. Using one or more of those references, complete the following table of physical constants:
