| − | A '''hydrocarbon''' (HC) is a substance that is made of [[carbon]] and [[hydrogen]] in the gaseous, liquid, or solid phase. The molecular structure of hydrocarbon compounds varies from the simplest to the very heavy and very complex. The first structures are [[methane]], [[ethane]], [[propane]] (used for fuel), [[butane]] (used in lighters), [[pentane]], [[hexane]], [[heptane]], and [[octane]]. | + | A '''hydrocarbon''' (HC) is a substance that is made of [[carbon]] and [[hydrogen]] in the gaseous, liquid, or solid phase.
