Cracking 0.0 / 5 ? ChemistryOrganic and Green ChemistryGCSEAQA Created by: NatmacCreated on: 04-02-19 18:08 What happens in cracking? In cracking, a large alkane is broken down, to produce smaller, more useful molecules 1 of 9 What can shorter chain alkanes are used for? Cars 2 of 9 What else is made from cracking? An Alkene 3 of 9 What are two types of cracking? Catalytic cracking and steam cracking 4 of 9 How do we do catalytic cracking? We use heat and a catalyst. The catalyst speeds up the reaction 5 of 9 How do we do steam cracking? We use heat and steam 6 of 9 What do Alkenes have? Alkenes have at least one double carbon to carbon covalent bond. 7 of 9 Are Alkenes more reactive or less reactive? More reactive 8 of 9 How do we test for Alkene? If we shake our Alkene with bromine water, then the bromine water became a colourless solution 9 of 9
