Diamond Methane Recap- Melting/Boiling Points Which molecule will have a higher melting and boiling point? A: Ethane B: Hexane Hydrocarbons The more carbon atoms a hydrocarbon has, the higher its melting and boiling point. Hydrocarbon Melting Point Boiling Point Phase at Room (oC) (oC) Temperature CH4 -182 -162 Gas C5H12 -130 36 Liquid C18H38 28 317 Solid Uses of Hydrocarbons Hydrocarbons have many uses. Solvents- liquids to dissolve Fuels for vehicles and other substances such as Plastics transportation. nail polish remover. Uses of Hydrocarbons Asphalt pavement on highways is made of hydrocarbons found in petroleum. Many candles Motor oil are made of consists of paraffin wax, a many solid made of hydrocarbons. hydrocarbons. These forms of The lighter transportation are burns butane. fueled by different Fuels for vehicles and mixtures of transportation. hydrocarbons. Sources of Hydrocarbons Hydrocarbons come from natural gas and crude oil. Sources of Hydrocarbons Hydrocarbon Source Use Alkanes Natural gas and Fuels, motor oil, asphalt, crude oil solvents Alkenes Natural gas and Fuels, raw material for making crude oil plastics, ripening fruit (ethene) Alkynes Natural gas and Welding gas (svetsning) crude oil Learning Goals Name the first 6 hydrocarbons in the alkane, alkene, and alkyne series.
