Heat of hydrogenation

If benzene is more stable than cyclohexane then why is the heat of hydrogenation of benzene negative, ie heat is released during the formation of cyclohexane from benzene ?




All hydrogenation reactions, not just for benzene, are exothermic. You can refer  [Why are hydrogenation reactions exothermic](https://chemistry.stackexchange.com/questions/44371/why-are-hydrogenation-reactions-exothermic) .
