CHEM 2125: Organic Chemistry Lab I

In this five-day lab course, students perform experiments that illustrate the principles learned in CHEM 2123.


Learning outcomes

  • Handle organic chemicals in a safe and competent manner.
  • Perform the standard techniques used in practical organic chemistry.
  • Carry out an organic preparation following a prescribed procedure.
  • Read and explain the information labels on chemical bottles.
  • Measure and report relevant physical properties of prepared compounds.
  • Identify selected organic unknowns.
  • Use the reference material found in the laboratory.
  • Describe the location and use of safety equipment in the laboratory
  • Explain the emergency procedures followed in the laboratory.

Course topics


  • Determination of melting point and refractive index
  • Recrystallization
  • Isolation of a naturally occurring compound from plant material
  • Simple and fractional distillation
  • Chromatography
    • Thin layer
    • Gas-liquid
  • Extraction, separation and derivative formation

Required text and materials

Students will be required to print their own laboratory manual prior to their first day in class. Other supplies will be provided during the lab. For safety reasons, students must wear closed shoes. No open-toed shoes or sandals are permitted in the labs. No contact lenses are to be worn. Safety goggles must be purchased for this lab.


To successfully complete this course, students must achieve a passing grade of 50% or higher on all laboratory reports and assignments. Students will also be graded on their lab technique and data book.

Students cannot miss more than two lab sessions or an incomplete grade will be assigned.
