Alcohols & Ethers
Learning Goals
I can use proper IUPAC naming to name, write formulas and draw structures of alcohols and ethers
I can differentiate alcohol and ether compounds by their names and structural formulas
I can describe some physical properties of alcohols and ether compounds
I can explain the types of chemical reactions that alcohols and ether compounds undergo and what products are formed as a result.

LESSON OVERVIEW (SPECIFIC EXPECTATIONS: B2.2, B2.4, B3.1, B3.2, B3.3)
Hook:
Creative Mind Mapping: Students will be separated into groups of 5 and will be required to create a mind map on the topic of Alcohols. They will be able to incorporate images, words, and phrases into their works and will then present it to the class. It is expected that students will primarily focus on the consumption of alcohol, however this will allow the teacher to clarify the term "alcohol" in chemistry.
Teaching Strategies:
1. Naming Alcohols Activity:

Teaching Strategies:
1. Naming Alcohols Activity:
- Make an Alcohol Chain – students will be given colour-coded cards with different alkyl groups (black) and hydroxyl groups (red). They will physically join or bond with each other to form alcohol chains as called out by the teacher. For example, Matthew has a methyl group, Mary has a CH2 group, and Levinia has a hydroxyl group. When the teacher asks students to make ethanol, the three students come together and form an ethanol chain
- Students will conduct an investigation to determine the physical properties of primary alcohols, including boiling point, melting points, and solubility in polar and non polar solvents.
- Use the following prezi presentation to introduce the alcohol and ether functional groups and to go through the IUPAC naming conventions and properties of alcohols and ethers. This is an excellent presentation that contains several examples and engaging graphics that helps students connect the topic to real life examples they have seen in everyday life. This presentation can be followed by a handout on the reactions of alcohols and ethers. For the visual learners in the classroom, it is best to illustrate reactions through molecular models in order to show how bonds are broken and reformed to create new products.
Consolidation:
Exit slip: Draw and name the ether compound that forms from the reaction of methanol and butanol.
