Module 4 | Energy
Focus 3: A variety of carbon compounds are extracted from organic sources
Lesson 1 | Fractional distillation
-
Describe the use of fractional distillation to separate the components of petroleum and identify the uses of each fraction obtained.
-
Perform a first-hand investigation and gather first-hand information using the process of fractional distillation to separate the components of a mixture such as ethanol and water.
Lesson 2 | Representing hydrocarbons
-
Identify and use the IUPAC nomenclature for describing straight-chained alkanes and alkenes from C1 to C8.
-
Plan, identify and gather data from secondary sources to model the structure of alkanes and alkenes C1 to C8.
-
Compare and contrast the properties of alkanes and alkenes C1 to C8 and use the term ‘homologous series’ to describe a series with the same functional group.
Lesson 3 | Properties of hydrocarbons
-
Explain the relationship between the melting point, boiling point and volatility of the above hydrocarbons, and their non-polar nature and intermolecular forces (dispersion forces).
-
Assess the safety issues associated with the storage of alkanes C1 to C8 in view of their weak intermolecular forces (dispersion forces).
-
Process and present information from secondary sources and use available evidence to identify safety issues associated with the storage of alkanes.
