1.	Enthalpy of hydrogenation of cyclohexene is -119Kj/mol and that of benzene is -208kJ/mol. Basedon these information, resonance energy of benzene can be calculated to be
Answer» -119Kj/MOL -238Kj/mol -149Kj/mol -565Kj/mol Solution : `DeltaH = -375kJ//mol` (theoretical ) ` DeltaH_(RE) = DeltaH_(Theo) - DeltaH_(EXP)` `=-357 - (208) = 149 KJ // mol`
