Answer:
Here are examples of properties or uses of three different hydrocarbons:
Methane (CH4):
Property: Methane is a colorless and odorless gas at room temperature. It is the primary component of natural gas.
Use: Methane is widely used as a fuel for heating, cooking, and electricity generation. It is also used as a raw material in the production of chemicals, such as methanol and hydrogen.
Ethene (C2H4):
Property: Ethene is a colorless gas with a slightly sweet odor. It is a highly flammable hydrocarbon.
Use: Ethene is a crucial feedstock in the petrochemical industry. It is used to produce various products, including plastics (polyethylene), solvents, synthetic fibers, and detergents.
Octane (C8H18):
Property: Octane is a colorless liquid hydrocarbon with a gasoline-like odor. It is relatively non-reactive and has a high energy content.
Use: Octane is a major component of gasoline, used as a fuel for internal combustion engines in vehicles. It provides the energy necessary for combustion and helps improve engine performance.
Please note that these are just a few examples, and hydrocarbons have diverse properties and uses across various industries.
