Crude Oil and Fuels Flashcards
What are alkanes
hydrocarbons that only have single bonds
how can you test for alkenes
alkenes turn orange bromine water colourless
describe reactivity of alkenes compared to alkanes
alkenes are much more reactive
what are alkenes used for
formation of polymers
what are alkenes
hydrocarbons with a double bond
what are products of cracking
-short chain alkanes
-alkenes
2 methods to carry out cracking
-steam cracking
-catalytic cracking
what is cracking
breaking down a hydrocarbon with a long chain into smaller molecules
name 4 materials produced from crude oil
-solvents
-lubricants
-polymers
-detergents
name 5 fuels produced from fractional distillation
-petrol
-diesel oil
-kerosene
-heavy fuel oil
-liquefied petroleum gases
what is a fraction
a group of hydrocarbons with similar chain lengths
how can different alkanes in crude oil be seperated
fractional distillation
how does flammability depend on chain length
longer the chain, lower the flammability
how does viscosity (thickness) depend on chain length
longer the chain, higher the viscosity
how does boiling point depend on chain length
longer the chain, higher the boiling point
