Crude oil Flashcards
What are hydrocarbons?
Fuels such as petrol and diesel
Made of Hydrogen and Carbon
Why aren’t hydrocarbons chemically bonded to one another?
No chemical bonds
How can crude oil be split up?
Fractional distillation
What is fractional distillation?
Crude oil is heated in the bottom of the fractionating column
It vaporises and rises up
Condenses at specific levels due to length of the molecule
What is crude oul mostly?
Alkanes
What are alkanes made up of?
Chains of carbon atoms
Surrounded by hydrogen atoms
What do different alkanes have?
Chains of different lengths
What are the first 5 alkanes?
Methane Ethane Propane Butane Pentane
Why are alkanes saturated?
Single bonds
What is the general formula of alkanes?
CnH2n+2
