C9 Crude oil and fuels
Crude oil, hydrocarbons and alkanes
what is crude oil?
what is a hydrocarbon?
what is the general formula for an alkane?
what are the first four alkanes and how many carbons does each have?
draw ethane
Fractional distillation and petrochemicals
how does fractional distillation separate the fractions of crude oil in terms of evaporation and condensation?
what are the fractions used for?
label the different fractions
Properties of hydrocarbons
how does how boiling point, viscosity and
flammability change with increasing molecular size?
The combustion of hydrocarbon fuels releases energy. During combustion, the carbon and hydrogen in the fuels are oxidised. The complete combustion of a hydrocarbon produces carbon dioxide and water.
write a balanced symbol equation for the
complete combustion
of ethane
write a balanced symbol equation for the
complete combustion
of propane
write a balanced symbol equation for the
complete combustion
of butane
what products are formed with
incomplete combustion
and why are these dangerous?
Cracking and alkenes
what is cracking?
describe in general terms the conditions
used for catalytic cracking
describe in general terms the conditions
used for steam cracking
what are the products of cracking and how are they useful?
how do you test for the presence of an alkene?
what is the general formula for a polymer?
which polymers are made from ethene and propene?
what is the general formula for an alkene?
write a balanced symbol equation for the cracking of decane into pentane + propene + ethene
draw ethene
