Mini Challenge

Constructing Molecular Models of Phenols

Students will form groups, each receiving materials to construct molecular models of distinct phenols. They will be tasked with accurately identifying and naming each phenol using IUPAC nomenclature.

1. Divide students into groups of 3 to 4 members.

2. Distribute molecular modeling kits to each group.

3. Provide a list of phenols for students to construct and name, including phenol (C6H5OH), 2-methylphenol (C7H8O), and 4-nitrophenol (C6H4(NO2)OH).

4. Instruct groups to build the molecular models of the specified phenols.

5. After building, each group must correctly identify and name the phenols using IUPAC nomenclature.

6. Encourage groups to present their models to the class, discussing the structure and nomenclature of each compound.

Enhance the ability to accurately identify and name phenols while fostering teamwork and practical application of acquired knowledge.

**Duration: 30 - 35 minutes
