The diagram illustrates the skeletal formula of cyclopropane. The enthalpy change of formation of cyclopropane is $+53.3\,\text{kJ mol}^{-1}$, while the enthalpy change of atomisation of graphite is $+717\,\text{kJ mol}^{-1}$. The bond enthalpy of H-H is $436\,\text{kJ mol}^{-1}$ and that of C-H is $410\,\text{kJ mol}^{-1}$. What value for the mean bond enthalpy of the C-C bond in cyclopropane can be determined from these data?
- A$187\,\text{kJ mol}^{-1}$
- B$315\,\text{kJ mol}^{-1}$
- C$351\,\text{kJ mol}^{-1}$
- D$946\,\text{kJ mol}^{-1}$
