Organic chemistry
Cracking and alkenes
hydrocarbons can be broken down (cracked) to produce smaller, more useful molecules
-
-
alkenes are more reactive than alkanes and react with bromine water, which is used as a test for alkenes
there is a high demand for fuels with small molecules and so some of the products of cracking are useful fuels
alkenes are used to produce polymers and as starting materials for the production of many other chemicals

-
-
most of the compounds in crude oil are hydrocarbons, which are molecules made up of hydrogen nd carbon atoms only
