This document outlines tasks for a chemistry lesson, including: 1) Building various molecules using molecular modeling kits, from simple to more complex organic compounds. 2) Students must learn to name alkanes and alkenes up to 6 carbons and understand different types of chemical formulas. 3) Completing pages from an organic chemistry workbook. 4) Defining different types of chemical formulas and representing molecular structures. 5) Experimenting in groups to determine the boiling points of different alkanes using a water bath. 6) Ranking provided alkanes by boiling point from highest to lowest, explaining reasons using structural properties.

1. Starter
• Mock reflection sheets / complete Module One
Feedback form – link to blog on fb page.
• Build the following molecules using molymods :• EASY : Methane, Propane, Butane
• MEDIUM : Butene, Cyclopropane.
• HARD : 2-chloropentane, ethanoic acid.

2. Objectives
• MUST: Name alkanes / alkenes ( up to C6 )
• SHOULD : Understand the differences
between empirical, molecular, structural,
displayed and skeletal formulae.
• COULD : Use geometry and overall polarity to
compare boiling points of unusual alkanes.

3. Task One
• Or Page 1 & 2 Organic Chemistry workbooks.

4. Task Two
• Empirical; simplest ratio of elements.
• Molecular; includes all atoms but does not
show arrangement.
• Structural; minimum possible representation
of structure.
• Displayed; 2D projection.
• Skeletal formulae; 3D structural formula.

5. Task Three
• As a class you are provided with 4 alkanes.
• Each team takes one alkane and, using a water
bath, establish its boiling point.
Alkane
Boiling Point

6. Task Four
• Place in order, with reasons, the highest
boiling to the lowest boiling.
• Words to include : Structure, shape,
hybridisation, intermolecular forces, boiling.
• Propane, Ethane, Cyclohexane, 1chlorobutane.
