Tests for Organic Compounds — Interactive Lesson (Ages 14–16)

Give pupils an unknown liquid and the tools to identify it like a chemistry detective. This 19-slide interactive lesson on tests for organic compounds takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Tests for Organic Compounds in GCSE Chemistry

This revision lesson brings together the key tests: bromine water and acidified manganate(VII) for unsaturation, ammoniacal copper(I) chloride for ethyne, sodium, sodium carbonate and acidified dichromate for alcohols and acids, and iodine, Benedict's and biuret food tests. Detective cases ask pupils to combine results to identify unknown compounds.

What Pupils Will Learn

• Test for C=C bonds with bromine water.
• Identify alcohols and carboxylic acids.
• Identify alkynes with ammoniacal copper(I) chloride.
• Test foods for starch, reducing sugar and protein.
• Use test results to identify unknown compounds.
