CH 221 - Lab for CH 220


Credit Hours: 1.0

This laboratory course includes: physical procedures, melting point determination, crystallization, distillation, steam distillation, experiments emphasizing basic techniques and procedures, handling organic chemicals, set up and use of organic equipment, safety, separations, purifications, measures of purity, and procedure for disposal of waste chemicals.

Course Outcomes
Upon the completion of this course, the student should be able to:

  • demonstrate an awareness of safety practices in the laboratory, and appreciate the historical significance of current technological advances;  
  • measure physical properties of organic structures such as melting and boiling points, index of refraction and density;                 
  • name hydrocarbons and other classes of organic compounds in accordance with the IUPAC system;        
  • correctly assemble and use ground glass components;
  • observe Free Radical Halogenation and measure the quantity and structure of reaction products;
  • isolate optically active components from natural products using Soxhlett and liquid/liquid extractions;
  • extract alkaloids from natural products and purify by sublimation;
  • be conversant with the operation and maintenance of vacuum pumps and flash evaporators;
  • demonstrate the use of cryogenic solids and liquids in the lab;
  • describe the production and reactions of Grignard reagents;
  • determine the composition of commercial analgesics through the use of thin layer chromatography;
  • synthesize and purify components of analgesics by recrystallization;
  • compare the effects and relative benefits of both simple and fractional distillation;
  • learn the use of Raschig rings; and
  • learn computer graphing techniques.
