Classic AP Requirement #22—Synthesis, Purification and Analysis of an Organic Compound
Students perform a quantitative esterification reaction to produce ethyl acetate. The lab consists of three parts—in Part 1, the ethyl acetate is prepared, in Part 2, the ethyl acetate is purified, and in Part 3, tests are performed to verify the identity of the ethyl acetate. The theoretical yield is then calculated and the percent yield is determined. Students receive hands-on experience with common organic chemistry techniques, such as refluxing, extractions, and distillation.
Complete for 24 students working in pairs.
