What is a Hydrocarbon?
A Hydrocarbon is a compound only containing Hydrogen and Carbon
They can have single and double bonds, meaning they can be
saturated or unsaturated.
They have a variety of chain lengths
Varied shapes
Many are flexible and can move whilst still having fixed van der Waals,
Covalent and Hydrogen bonds.…read more

Here's a taster:

What is an Alkane?
An Alkane is the simplest form of a hydrocarbon. Each Carbon atom
has 4 bonded pairs.
They have single bonds, therefore are saturated.
They are insoluble in water
Have a variety of chain lengths
Rotate and bend easily
Have the general formula CnH2n+2
As the molecules get longer the more energy it takes to remove the
inter/intramolecular forces holding the atoms together (either van der
waals, covalent or hydrogen) therefore boiling point increases.
Release large amounts of energy.…read more

What is crude oil?
Crude oil is a mixture of long and short-chain hydrocarbons
It if a non-renewable fossil fuel
Crude oil , once in shorter chains can be condensed into Petrol,
Kerosene, gas oil and many more.
we use shorter chain hydrocarbons in everyday life, This means that
we have to find a way to shorten or separate the hydrocarbons, this is
done by:
Cracking
Fractional Distillation…read more

Here's a taster:

Cracking
This involves breaking the C-C bonds in the Hydrocarbon.
The long, heavy hydrocarbons are passed over a catalyst and a
very high temperature, this breaks the bonds forming smaller
alkenes and Alkanes.…read more
