SKILL P~PLANNING Input Variables Alcohol This is the variable I am going to investigate. An increase in the length of carbon-carbon chains will result in an increase of energy given out. This is due to the longer hydrocarbons having, a greater attraction to each other. Therefore more energy is needed to break them down so more energy is given out since the reaction is exothermic. Volume of Alcohol A greater volume means more molecules of the alcohol. More molecules will mean more atoms, hence more carbon-carbon chains. As is described above more carbon-carbon chains in this experiment will mean more energy. Therefore to keep this variable constant each alcohol will have the same number of molecules. Isomers of Alcohol Isomers may have different structures., and they may have different properties. We know that branched chains have lower boiling points then straight ones. Therefore to make sure that isomers do not effect the experiment only one isomer from...
