Carbon monoxide and water form. CO poisonous 5 of 8 Cracking the breakdown of large chain hydrocarbons into small chain hydrocarbons 6 of 8 How to test for an alkane Use bromine water. The alkene reacts w/ the bromine, and the Br adds to the carbon atoms either side of the double bond-the double bond breaks. 7 of 8 What is Crude Oil Mixture Of hydrocarbons formed by dead animals and plants, fossil fuels 8 of 8
