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 ?

What do you mean by "benzene is more stable than cyclohexane". Can you provide a source for that statement? – Buck Thorn Apr 04 '19 at 07:54

If it is exothermic means cyclohexane must be more stable than benzene right? But it is not so. How is that possible? – Anonymous Apr 04 '19 at 13:26

"But it is not so". By what measure is it not so? What makes you say, "benzene is more stable than cyclohexane". – Buck Thorn Apr 04 '19 at 14:22

Because benzene is aromatic? That's what others told me but I'm not sure. – Anonymous Apr 08 '19 at 04:24

All hydrogenation reactions, not just for benzene, are exothermic. You can refer Why are hydrogenation reactions exothermic .
