Consider benzene (\(C_6H_6\)) in the gas phase.

(a) Write the reaction for breaking all the bonds in \(C_6H_6\)(g), and use data in Appendix C to determine the enthalpy change for this reaction.

(b) Write a reaction that corresponds to breaking all the carbon–carbon bonds in \(C_6H_6\)(g).

(c) By combining your answers to parts (a) and (b) and using the average bond enthalpy for C -- H from Table 8.4, calculate the average bond enthalpy for the carbon–carbon bonds in \(C_6H_6\)(g).

(d) Comment on your answer from part (c) as compared to the values for C – C single bonds and C == C double bonds in Table 8.4.
