Different length hydrocarbons
list four alkanes
methane, ethane, propane, butane
Describe who crude oil is made
the remains of dead plankton and other animals and plants buried in sand and mud over long periods of time
What are the uses of crude oil?
fuel for transport e.g petrol and diesel
What are the four things crude oil can be used for?
Polymers, lubricants, solvents and detergents
What is the combustion equation?
hydrocarbon + oxygen ➡️ carbon dioxide + water
What is the balanced symbol equation for combustion?
CH2 + 2O2 ➡️ CO2 +2H2O
How does the length of the hydrocarbon affect the boiling point?
The longer the hydrocarbon, the higher the boiling point.

When testing for alkenes with bromine water, what is the colour change?
orange to colourless
How does the length of the hydrocarbon affect the viscosity?
the longer the hydrocarbon the MORE viscous it is
