Fractional Distillation is a method used in industry to separate different sized hydrocarbons (long chains that consist of hydrogen and carbon). This is useful as it mean...

The electrostatic forces of attraction between the shared pair of bonded electrons and the positively charged nuclei hold the atoms together.

Heat the oil up until it is a vapour Pass into fractionating column Negative temperature gradientHydrocarbons of different lengths have different boiling points They condense at different heights and are ...

Ionic bonding: When a metal loses electron(s) and a non-metal gains electron(s) to achieve a full outer shell For example, sodium chloride (NaCl) Points to make: Which atom lose...

Crude oil is a mixture of hydrocarbons with varying length carbon chains. The main method used to separate these is fractional distillation. The crude oil is heated, then placed inside a fractionating col...
