Mini Challenge

Building Molecular Models of Phenols

Students will form groups, and each group will be given materials to build molecular models of different phenols. They will need to correctly identify and name each phenol using IUPAC nomenclature.

1. Divide students into groups of 3 to 4.

2. Hand out molecular modeling kits to each group.

3. Provide a list of phenols that students need to build and name, such as phenol (C6H5OH), 2-methylphenol (C7H8O), and 4-nitrophenol (C6H4(NO2)OH).

4. Guide the groups as they construct the molecular models.

5. Once complete, groups must accurately identify and name each phenol using IUPAC rules.

6. Encourage students to present their models to the class, elaborating on the structure and nomenclature of each compound.

Foster the ability to correctly identify and name phenols, while also encouraging teamwork and the practical application of learned concepts.

**Duration: 30 - 35 minutes

Evaluation Exercises

1. Provide a list of organic compounds for students to identify which are phenols and name them using IUPAC nomenclature.
