What is crude oil?
Crude oil is a fossil fuel. It is useful because it contains hydrocarbons, substances that contain hydrogen and carbon atoms. Hydrocarbons can produce a lot of energy when burned, thus making it suitable for providing for energy needs.
Here are some hydrocarbons present in crude oil:
Paraffins or Alkanes
- They have a general formula of CnH2n+2
- The molecules are straight- or branched-chain
- They can be in gaseous or liquid state at room temperature depending on the type of molecule

- They have a general formula of C6H5 - Y (Y is a longer, straight molecule)
- They have ringed structures with one or more rings
- The rings contain 6 carbon atoms with double and single bonds alternating between the carbon atoms
- They are usually liquids at room temperature

Naphthenes & Cycloalkanes
- They have a general formula of CnH2n
- They have ringed structures with one or more rings
- The rings contain single bonds between the carbon atoms
- They are usually liquids at room temperature
