Functional Groups

Where the chemistry happens

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Functional groups (OH, C=O, COOH, COOR, NH₂...) carry a molecule’s chemistry.
• Isomers can belong to different families (alcohol vs ether).

Steps

1. The working parts
2. Alcohol or acid?
3. Three isomers, two families
4. Name the group
5. Pear drops
