positron Posted September 18, 2005 Share Posted September 18, 2005 Are there any properties of hydrocarbons that when graphed will produce a curve?(eg. heat capacity, density, etc.) thanks Link to comment Share on other sites More sharing options...

positron Posted September 18, 2005 Author Share Posted September 18, 2005 well, versus a variable such as temperature or volume, anything really, as long as the graph produced is a curve Link to comment Share on other sites More sharing options...
Halash Posted September 18, 2005 Share Posted September 18, 2005 pattern: methane - 1 carbon, 4 hydrogen. 1/4 ratio ethane - 2 carbon, 6 hydrogen. 1/3 ratio propane - 3 carbon, 8 hydrogen. 1/2.666.... ratio butane - 4 carbon, 10 hydrogen. 1/2.5 ratio pentane - 5 carbon, 12 hydrogen. 1/2.4 hexane - 6 carbon, 14 hydrogen. 1/2.3333.... heptane - 7 carbon, 16 hydrogen. 1/2.857..... octane - 8 carbon, 18 hydrogen. 1/2.25 basically, continue to add one carbon and 2 hydrogen. i believe that will make a curve octane is heavier than methane. from methane to octane, the density, and melting point is raised Link to comment Share on other sites More sharing options...
