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





Term
Definition
Example
Homologous series
 In chemistry, a homologous series is a series of organic compounds with a similar general formula.

 All the Alkanes.
Hydrocarbon
an organic compound containing only carbon and hydrogen.

 Methane
Saturated hydrocarbon
A hydrocarbon that has only single bonds between each carbon atom

 all the Alkanes
Unsaturated hydrocarbon
Unsaturated hydrocarbons are hydrocarbons that have double or triple covalent bonds between adjacent carbon atoms

 all the Alkenes
General formula
 Mathematical formula to show the ratio of one element to another

 CnH2n+2
Isomerism
In chemistry, isomers are compounds with the same molecular formula but different structural formulas

 2, Methylbutane
