Organic Functional Groups

Activity-Based Learning: Prior to the lesson, find out about the general formula, properties and nomenclature of alkanes and other hydrocarbons.
Talk for Learning:
- In a whole class discussion, talk about organic reactants (saturated, unsaturated compounds, electrophiles, nucleophiles, free radicals), types of organic reactions, factors that affect organic reactions, homolytic and heterolytic fission, functional groups and isomerism (chain, position, functional group, geometrical isomerism)
- Generate the formulae and structure of the first 10 members of the alkanes series using their general molecular formula.
Activity-Based Learning:
- Model each isomer of alkane (C4 and C5).
- Apply IUPAC rules to name straight chain (C1 - C10) and branched chain alkanes up to C6.
Inquiry-Based Learning:
- Investigate the physical properties of alkanes such as melting points, boiling points, density, volatility and solubility.
- Explain the low reactivity of alkanes in terms of bond enthalpies and bond polarity.
- Describe using equations, complete and incomplete combustion reactions of alkanes and discuss the effect of their products to the environment (greenhouse effect and global warming), release of CO and the use of catalytic converter to minimize the pollution.
Collaborative Learning:
- Discuss the effect of other products of burning fuel (formation of acid rain).
- Describe using equations, the reactions of methane with chlorine. Discuss the effect of the product (CFCs) on ozone layer.
- Discuss free radical mechanism of the reaction of methane and chlorine.
- Discuss cracking and reformation of alkanes.
- Discuss the uses of alkanes. (i.e., Uses of the various petroleum fractions obtained from fractional distillation of crude oil).
