Students:

● investigate the nomenclature of organic chemicals, up to C8, using IUPAC conventions, including simple methyl and ethyl branched chains, including: (ACSCH127)

– alkanes

– alkenes

– alkynes

– alcohols (primary, secondary and tertiary)

– aldehydes and ketones

– carboxylic acids

– amines and amides

– halogenated organic compounds

● explore and distinguish the different types of structural isomers, including saturated and unsaturated hydrocarbons, including: (ACSCH035)

– chain isomers

– position isomers

– functional group isomers

Hydrocarbons

IQ2: How can hydrocarbons be classified based on their structure and reactivity?

Students:

● construct models, identify the functional group, and write structural and molecular formulae for homologous series of organic chemical compounds, up to C8 (ACSCH035) :

– alkenes

– alkynes

● conduct an investigation to compare the properties of organic chemical compounds within a homologous series, and explain these differences in terms of bonding (ACSCH035)

● analyse the shape of molecules formed between carbon atoms when a single, double or triple bond is formed between them

● explain the properties within and between the homologous series of alkanes with reference to the intermolecular and intramolecular bonding present
