Describe the Kekule and delocalised model of benzene and explain some of the reasons why the kekule is disproved

Kekule Model - 6 membered carbon ringComposed of carbon atoms joined together by alternating single and double bonds
Delocalised Model - A planr cyclic hydrocarbon composed of 6 carbon atoms and 6 hydrogen atomsEach carbon atom bonded to 2 others and a hydrogenSpare, delocalised electon located in p-orbital, can overlap sideways to form pi bond.
Reasons - 1 = Unreactive, 2 = Carbon-carbon bond lengths, 3 = Enthalpy of hydrogenation
