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.

Synthesis, Isolation and Purification of an Ester Inquiry Guidance and AP® Chemistry Curriculum Alignment Transition Guide available! Follow the link in Resources to find this valuable publication that lets you adapt this classic AP Chemistry experiment for guided-inquiry and correlate with the AP Chemistry curriculum framework.

Performance Expectations

HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
