... change of combustion of a number of alcohols so that I can investigate how and why the enthalpy change is affected by the molecular structure of the alcohol. Also I am going to investigate branched and unbranched alcohols to compare the enthalpy changes and to find out whether the enthalpy changes of combustion is affected by the position of the alcohol group. In this experiment, I am going to be using primary and secondary alcohols. Here are the balanced equations for the complete combustion of all the alcohols I'll be using. Butan-1-ol: C4H9OH(l) + 6.5O2(g) 4CO2(g) + 5H2O(l) Butan-2-ol: C4H9OH(l) + 6.5O2(g) 4CO2(g) + 5H2O(l) Pentan-1-ol: C5H11OH(l) + 5O2(g) 5CO2(g) + 6H2O(l) Pentan-2-ol: C5H11OH(l) + 5O2(g) 5CO2(g) + 6H2O(l) Hexan-1-ol: C6H13OH(l) + 6O2(g) 6CO2(g) + 7H2O(l) Hexan-2-ol: C6H13OH(l) + 6O2(g) 6CO2(g) + 7H2O(l) Heptan-1-ol: C7H15OH(l) + 7O2(g) 7CO2(g) + 8H2O(l) Heptan-2-ol: C7H15OH(l) + 7O2(g) 7CO2(g) + 8H2O(l) Octan-1-ol: C8H17OH(l) + 8O2(g) 8CO2(g) + 9H2O(l) Octan-2-ol: C8H17OH(l) + 8O2(g) 8CO2(g) + 9H2O(l) Apparatus In this experiment I am going to use the ...
