3.1 I can explain the terms homologous series, hydrocarbon, saturated, unsaturated, general formula and isomerism


Term
Definition
Example
Homologous series
 Members of the same series, or family having similar chemical properties.

 alkanes
Hydrocarbon
 A hydrocarbon is a compound containing only hydrogen and carbon.

 crude oil, methane, ethane, propane, butane, pentane
Saturated hydrocarbon
 Molecules with a single bond throughout the whole structure

 Any Alkanes (Methane)
Unsaturated hydrocarbon
 Molecule with a double/triple bond

 Any Alkenes
(Ethene)
General formula
 A mathematical formula to express the number of carbon and hydrogen atoms in a molecule 

C nH2n+2
Isomerism
 Molecules having the same formula, but are structured differently.

 2,2 Dimethylpropane

  1. 3.1 homologous series has the same general formula, for saturated and unsaturated hydrocarbons the bond you need to refer to is the carbon carbon bond
