Alkanes Physical properties: The chemistry of one C paper compounds is called fundamental chemistry. there argon millions of organic chemics, entirely they can be split into groups called homological series. solely members of a particular series allow for have analogous chemical properties and can be stand for by a general formula. The paraffin wax series is the simplest homologous series. The main solution of alkanes is from crude oil. Alkanes argon covalent compounds. They ar hydro light speeds, which means they obtain hydrogen and carbon. The general formula for an alkane is . Properties and uses of alkanes: Name of alkane: Â Â Â Â Â Â Â Â melt down point oC: Â Â Â Â Â Â Â Â simmering point oC: Â Â Â Â Â Â Â Â Density g/cm3: Â Â Â Â Â Â Â Â bring up at dwell temperature: Methane CH4 Â Â Â Â Â Â Â Â -182 Â Â Â Â Â Â Â Â -162 Â Â Â Â Â Â Â Â 0.42 Â Â Â Â Â Â Â Â flatulence Ethane C2H6 Â Â Â Â Â Â Â Â -183 Â Â Â Â Â Â Â Â -88 Â Â Â Â Â Â Â Â 0.55 Â Â Â Â Â Â Â Â Gas Propane C3H8 Â Â Â Â Â Â Â Â -188 Â Â Â Â Â Â Â Â -42 Â Â Â Â Â Â Â Â 0.58 Â Â Â Â Â Â Â Â Gas Octane C8H18 Â Â Â Â Â Â Â Â -57 Â Â Â Â Â Â Â Â 126 Â Â Â Â Â Â Â Â 0.72 Â Â Â Â Â Â Â Â Liquid The first four alkanes argon ordnancees at room temperature. Alkanes with 5-17 carbon atoms are liquids. Alkanes with 18 or more carbon atoms are solids. As the number of carbon atoms increases, the break up points, boiling points and densities increases. They are insoluble in water unless dissolve in organic solvents such as benzene. Their chemical reactivity is poor.
The C-C bond and C-H bond ar e very bullocky so alkanes are not very rea! ctive. They will run low out inflameion. Burning alkanes in air (oxygen) produces water and carbon dioxide. The reactions are very ex some othermic (give out agitate energy), so alkanes in crude oil and natural gas are widely used as heating fuels. For font: If alkanes combust in too little air, carbon monoxide may form. This is heavy and can cause death. Cracking alkanes The lighter fractions (for example, petrol) are in giant demand. The heavier fractions are not so usable but alas chemists have to be able to change these heavier fractions into petrol and other useful products, due to...
