Why is carbon special
Group 4 on the periodic table Each carbon atom can form four covalent bonds to other atoms Can be single, double and triple bonds
What is a hydrocarbon
A compound containing carbon and hydrogen only
What is a saturated hydrocarbon
Has single bonds only, as shown in the structure of methane
What is an unsaturated hydrocarbon
Contains carbon-carbon multiple bonds, as shown in the structures but-2-ene and propyne
What is a homologous series
A family of compounds with similar chemical properties whose successive members differ by the addition of a -CH2- group
What is the simplest homologous series

What are the first three members of the alkanes
Methane Ethane Propane
