The enthalpy change of formation of cyclopropane is +53.3kJmol–1 and the enthalpy change of atomisation of graphite is +717 kJ mol–1.
The bond enthalpy of H–H is 436kJmol–1 and of C–H is 410kJmol–1.
What value for the average bond enthalpy of the C–C bond in cyclopropane can be calculated
from this data?
