The concept of resonance explains various properties of compounds.The molecules with conjugated system of pi bonds, are stabilized by resonace and have low heat of hydrogenation.Hyperconjugative stabilization also decreases heat f hydrogenation.In aromic rings a functional group with a lone pair of electron exerts +m effect. Some functional groups like -NO, -NC, -CH=CH_2 can function both as electron releasing (+m,+R) or electron withdrawing (-m,-R) groups.More extended conjugation provides more stabilization. The most stable carbocation is :
