Alkenes
Reactions with alkenes
Oxidation
-
with cold KMnO4
Alkenes are mixed with cold acidified KMnO4, which acts as the oxidising agent

-
dehydrohalogenation
Formation of alkenes
-
Cracking
- the alkane is then heated to 450°C-750°C at 70atm
- heated alkane is passed over Al2O3 catalyst
- Long alkane chain is sent to a steel vacuum chamber to remove oxygen
