CHEM 2125: Organic Chemistry Lab I

Note: This course is offered face-to-face (laboratory, clinical) in a laboratory setting.Labs are held in either May, June or July at Thompson Rivers University, Kamloops, BC. Accommodation may be available at campus residences. TRU-OL reserves the right to cancel a lab section in the event the minimum student enrolment is not obtained by the registration dead-line.

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

Objectives

By the end of this course, students should be able to:

  • 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.

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.

Assessments

All required laboratory reports and assignments must be submitted, with 50% or more required on each. 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.
