Front (Question)
Compare benzene and the theoretical molecule cyclohexa-1,3,5-triene in terms of: * stability * shape * carbon–carbon bond lengths. For each of these properties, suggest reasons for any differences. (5)
Back (Answer)
• benzene is more stable than cyclohexa-1,3,5-triene • the enthalpy of hydrogenation of benzene is 152 kJ mol^-1 less exothermic • due to the delocalisation of electrons in benzene • both are planar • benzene has equal C-C bond lengths while cyclohexa-1,3,5-triene has bonds of different lengths
