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

Term	Definition	Example
Homologous series	A group of hydrocarbons with the same type of formula	Alkane
Hydrocarbon	A compound that is made out of carbons and hydrogens	Crude Oil
Saturated hydrocarbon	A saturated hydrocarbons only contains single bonds	Methane  part of the Alkanes
Unsaturated hydrocarbon	An unsaturated Hydrocarbon contains single and double( covalent ) bonds.	Ethene part of the Alkene
General formula	A mathematical formula showing the ratio of atoms.	For Alkenes C(n) H(n+2)
Isomerism	An Isomer is a molecule with the same molecular formula with a different atomic arragenment which results into different physical properties.	2,2 Dimeythelprotane
