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


Term
Definition
Example
Homologous series
 having the same functional group but differing in composition by a fixed group of atoms
 alkane
Hydrocarbon
 Compound of hydrogen and carbon

 Alkenes, alkanes
Saturated hydrocarbon
 Have single bonds

 alkanes
Unsaturated hydrocarbon
 Have double and/or   single bonds

 alkenes
General formula
 Series it shows the relationship between the number of C atoms and H atoms in the compounds

  for Alkanes it is CnH2n+2
for alkene it is CnH2
Isomerism                   
 compounds with the same formula but a different arrangement of atoms in the molecule and different properties
 2,2dimethylpropane
