Recall that hydrocarbons are compounds that contain carbon and hydrogen onlyAn unsaturated hydrocarbon is a compound which contains only carbon and hydrogen atoms and has a carbon – carbon double bond
a complex mixture of hydrocarbons containing molecules in which carbon atoms are in chains or rings; an important source of useful substances
Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. The carbon is released as soot .

Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide.
Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas. ... Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen.
Many fossil fuels contain sulfur impurities. When these fuels are burned, the sulfur is oxidised to form sulfur dioxide. This sulfur dioxide then dissolves in droplets of rainwater to form sulfurous acid.
Advocates for the use of hydrogen fuel cells posit that unlike other sources of power, these fuel cells do not emit harmful carbon emissions in the air that cause pollution and affect global warming. Although the chemical process involves burning hydrogen, it emits water, heat and other emissions but not carbon.
All fossil fuels are nonrenewable, but not all nonrenewable energy sources are fossil fuels. Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago
Lighter fractions are more useful and therefore more in demand. The large hydrocarbon molecules in the heavier fractions can be broken down into smaller, more useful molecules.

Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits and other organic materials.
Crude oil separations have different boiling points, the substances in crude oil can be separated using fractional distillation.

Solubility in water. In general, organic compounds are covalent and insoluble in water
A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series.
Combustion is burning a fuel in oxygen, which gives out heat energy and is called an exothermic reaction. Our main source of fuel is from fossil fuels.
Nitrogen oxides. When fuels are burned in vehicle engines, high temperatures are reached. At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide
Sulfur dioxide. Fossil fuels naturally contain sulfur compounds. ... When sulfur dioxide dissolves in water droplets in clouds, it makes the rain more acidic than normal. This is called acid rain
