Cracking Flashcards
What is cracking?
Cracking is the process used to convert a long chain alkane into shorter chain hydrocarbons / alkane
What are the two ways we can do cracking?
The two ways we can do cracking are catalytic cracking and steam cracking.
What are the conditions needed for catalytic cracking?
The conditions needed for catalytic cracking are a high temperature and a catalyst.
What is the difference between an alkene and an alkane?
Alkene may have double covalent bonds.
Why do long chain hydrocarbons such as alkanes not make good fuel?
They are not very flammable.
What are the conditions needed for steam cracking?
The conditions needed for steam cracking are a high temperature and steam.
Why are alkenes such important chemicals?
Alkenes are such important chemicals as they are used to make polymers, they are also used as a starting material to produce other chemicals.
What’s more reactive ALKANES or ALKENES?
Alkenes are more reactive than alkanes.
EXTREMELY IMPORTANT:
What is the test for alkenes?
We can test for alkenes using bromine water. We shake the bromine water and the potential alkene in a test tube and if it turns colourless then that means an alkenes present.
