reaction between alkane and alkene
substitution reaction
photochemical reactions
CH4+Cl2->CH3Cl+HCl condition：sunlight
Alkane to Alkene+alkane/hydrogen
Name：Catalytic Cracking
condition：heat（500 °C）+catalyst
Alkene to Alkane
（1）add bromine（2）add hydrogen
condition：bromine：i forget hydrogen：300 °C+nickel
definition
hydrocarbons：organic compounds that contain carbon and hydrogen only
saturated*only have single bond
unsaturated: have double bond or three bond
homologous：series of compounds with the same functional group
isomers：compounds that have the same molecular formula but different structural formulae
polymerisation
large molecules built up from many smaller molecules called monomers
repeating unit：a group of monomer which the double bond is broken
Polymer
petroleum
