Here's a taster:

The bigger the molecule:
· The less volatile it is
· The higher the boiling point (so it condenses lower in a
fractionating column)
· The less flammable it is
· The more viscous it is…read more

Here's a taster:

The complete combustion of a hydrocarbon in oxygen will
produce carbon dioxide and water as waste products, as well
as energy
Hydrocarbon+ oxygen carbon dioxide + water + energy
When there is a large
supply of oxygen, this is
known as complete
combustion…read more

Here's a taster:

Incomplete combustion of a hydrocarbon occurs when there
isn't enough oxygen. It will produce carbon dioxide, water,
carbon monoxide and carbon as waste products, as well as
energy
Hydrocarbon+ oxygen carbon dioxide + water + carbon monoxide + carbon + energy
When there is a large
supply of oxygen, this is
known as complete
combustion…read more

Bonds where
atoms share
electrons
Crude oil contains alkanes. These are chains of carbon atoms
joined to hydrogen atoms by single covalent bonds. Different
alkanes have chains of differing lengths.
The formula for alkanes is CnH2n+2, with `n' being the number of
carbon atoms.
Alkanes don't decolourise Alkanes are called Alkanes produce carbon

Here's a taster:

Crude oil also contains some alkenes. These are hydrocarbons
with one or more double covalent bonds. The formula for
alkenes containing one double bond is CnH2n, with `n' being the
number of carbon atoms.
They decolourise bromine Alkenes are called Alkenes can form polymers
