Structures and Nomenclatures Challenge

Students will work in groups for a hands-on activity where they will construct molecular models of acyl halides using modeling kits or recyclable materials. They will then correctly name each model following IUPAC nomenclature rules.

1. Divide the class into groups of 4 to 5 students.

2. Provide each group with modeling kits or recyclable materials (toothpicks, styrofoam balls, etc.).

3. Give each group a list of acyl halides for whom they need to build corresponding molecular models.

4. Once the models are built, each group will name the compounds according to IUPAC nomenclature.

5. Groups will present their models and names to the class, explaining the process they followed.

Apply IUPAC nomenclature rules for acyl halides practically, enhancing teamwork and communication skills.
