Consider benzene (C6H6) in the gas phase. A) Write the reaction for breaking all the bonds in C6H6(g), use delta H formation data to calculate enthalpy for this reaction. B) Write the reaction that corresponds to breaking all of the carbon-carbon bonds in C6H6(g). C) By combining your answers in A and B, and using average bond enthalpies for C-H, calculate average bond enthalpies of the carbon-carbon bonds in C6H6(g).
