Study Notes
Alkanes Overview
- Alkanes are hydrocarbons with single bonds and a general formula of CnH2n+2.
- They are saturated compounds, meaning they contain the maximum number of hydrogen atoms.
Methane
- Simplest alkane with the formula CH4.
- Colorless, odorless, and highly flammable.
- Primary component of natural gas.
Ethane
- Second simplest alkane with the formula C2H6.
- Colorless, odorless gas found in petroleum and natural gas.
Propane
- A three-carbon alkane with the formula C3H8.
- Flammable gas often used as bottled fuel, widely used for heating and cooking.
Butane
- Four-carbon alkane represented as C4H10.
- Flammable gas found in petroleum; commonly stored as a liquid in pressurized containers for easier transport and use.
Pentane
- Five-carbon alkane denoted by C5H12.
- A volatile liquid hydrocarbon used in various petroleum-based solvents.
Hexane
- Six-carbon alkane with the formula C6H14.
- A clear, colorless liquid often used as a non-polar solvent in laboratories and industry.
Heptane
- Seven-carbon alkane best known as C7H16.
- Colorless liquid derived from petroleum, commonly used in fuel applications.
Octane
- Eight-carbon alkane indicated by C8H18.
- Colorless and flammable, primarily obtained during the refining of petroleum, significant for its role in gasoline formulations.
Nonane
- Nine-carbon alkane with the formula C9H20.
- Colorless liquid hydrocarbon present in petroleum spirit, useful in industrial applications.
Decane
- Ten-carbon alkane represented as C10H22.
- Colorless liquid mainly found in kerosene and other petroleum products, frequently utilized as a solvent and fuel.
