Study Notes
Definition and Characteristics of Hydrocarbons
- Hydrocarbons are organic compounds consisting entirely of hydrogen and carbon.
- They are examples of group 14 hydrides.
- Hydrocarbons are generally colourless and hydrophobic.
- They usually have a faint odor, similar to that of gasoline or lighter fluid.
Forms and Phases of Hydrocarbons
- Hydrocarbons can exist in various molecular structures and phases.
- They can be gases (e.g., methane and propane).
- They can be liquids (e.g., hexane and benzene).
- They can be low melting solids (e.g., paraffin wax and naphthalene).
- They can be polymers (e.g., polyethylene and polystyrene).
Hydrocarbons in Fossil Fuels
- In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas, and coal.
- It also includes their hydrocarbon derivatives and purified forms.
Energy Source and Applications
- Combustion of hydrocarbons is the main source of the world's energy.
- Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.
Environmental Impact
- Most anthropogenic (human-generated) emissions of greenhouse gases are either carbon dioxide released.
