Cracking and alkenes
Cards in this deck (9)
- 1hydrocarbons can be cracked to produce whatsmaller, more useful molecles
- 2what methods are there of crackingcatalytic cracking and steam cracking
- 3what is catalytic crackingheavy oil is passed through metal chambers under pressure and high temperature in the presence of catalysts. This boiling breaks up long-chain oil molecules into simpler short-chain molecules.
- 4what is steam crackingSteam cracking is an uncatalyzed process, steam is added to long-chain hydrocarbons. This way lowers the force of the hydrocarbons so that condensation reactions are made lower.
- 5what are the products of crackingalkanes and alkenes
- 6what do alkenes react withbromine water, it turns from orange to clear when they are reacted together
- 7what is there a high demand for in fuelfuels with short chain molecules
- 8what are alkenes used to producepolymers (plastics)
- 9why is cracking usefulbecause we depend on having lots of fuel with a high energy value and cracking will help provide us with that
