1.	Using the following data, calculate the heat of combustion of cyclohexatrieneandalso find the resonance energy of benzene. `Delta_(C)H^(ɵ)` (Benzene)`=-789kcal mol^(-1)` Combustion contribution `(C-H)=-54.0kcal` Combustion contribution `(C-C)=-49.3kcal` Combustion contribution `(C=C)=-117.7kcal` Strategy: First write a balanced equation for the combustion of one mole of cyclohexatriene: Nowusing the structure, calculate the combution contribution for each bond and do the total for the molecule.
Answer» Three `C=C` bonds`=3xx(-117.7)=-353.1kcalmol^(-1)` Three `C-C` bonds`=3xx(-49.3)=-147.9kcalmol^(-1)` Six `C-H` bonds`=6xx(-54.0)=-324.0kcalmol^(-1)` `overline(S um=-825.0kcalmol^(-1))` Thus, the calculated heat of combustion for cyclohexatriene is `-825.0kcalmol^(-1)` Defference`=[(-789.1 kcal mol^(-1))-(-825.0 kcal mol^(-1))]` `=35.9 kcal mol^(-1)`
