Question Answer
what is cracking? the reaction used in the oil industry to break down large hydrocarbons into smaller, more useful ones.
Explain the ways cracking can be done? cracking can be done in 2 ways: 1) By heating a mixture of hydrocarbon vapours and steam to a very high temperature. 2) By passing hydrocarbon vapours over a hot catalyst
What reaction is cracking? Thermal Decompositon
Alkanes are... Saturated hydrocarbons
Alkenes are... Unsaturated hydrocarbons.
What is the test for unsaturated hydrocarbons? Unsaturated hyrdrocarbon+ Bromine water- colourless solution
What is the test for saturated hydrocarbons? saturated hydrocarbons+ Bromine water- orange (no reaction)
What does cracking produce? Cracking produces saturated hydrocarbons which are used as fuels
How is ethene made into poly(ethene)? When alkene molecules join together, the double bond between the carbon atoms in each molecule "opens up". It is replaced by single bonds as thousands of molecules join together. this reaction is called polymerisation.
