alkanas
Alkanes, also known as alkanas in some languages, are a family of saturated hydrocarbons consisting solely of carbon and hydrogen atoms connected by single bonds. For acyclic alkanes, the general formula is CnH2n+2, where n is the number of carbon atoms.
They include straight-chain alkanes (n-alkanes) and branched alkanes (isoalkanes). The simplest members are methane (CH4), ethane
Physical properties: Alkanes are generally colorless, odorless liquids or gases at room temperature and are nonpolar,
Occurrence and production: They are the main components of natural gas and petroleum. They are obtained by
Chemical properties: Alkanes are relatively unreactive; typical reactions include combustion to CO2 and H2O, and substitution
Safety and environment: They are highly flammable and can form explosive mixtures with air; methane is a
