Catalog Course Description

Introduction to organic laboratory techniques such as melting point, crystallization, distillation, thin layer chromatography, extraction. Synthesis of an ether and an alkene. 54 lab hours.

Course Objectives

  • Know the concept of the techniques used in organic chemistry synthesis - such as melting point, boiling point, crystallization, TLC, and extraction.
  • Balance a synthesis reaction such as preparation of an ether and an alkene.
  • Set-up the required instrumentation for the synthesis such as distillation apparatus. Use melting point instrument, Vacuum filtration set-up, and use separatory funnel properly.
  • Purify the product by distillation, crystallization, and extraction.
  • Verify the purity of the product by running the sample through the IR spectrometer provided in the lab.

Suggested Reading Other Than Required Textbook


Examples of Required Writing Assignments

Pre-lab. Describing procedure for recrystallization, including clean up and diagram of the experimental set up. Lab report. Describing of the results of the experiment such as % recovery of the solute. How to improve the % recovery. Discuss the potential of errors in the technique used.

Examples of Outside Assignments

Reading the discussion for the assigned experiment such as recrystallization. Choice and quantity of solvent has to be learned. The interaction of solvent and solute must be known.
