   All six carbon-carbon bonds in benzene have the same length, intermediate between a single and a double bond. This shows that:
   1. ABenzene is a mixture of two different compounds that constantly convert into each other faster than they can be separated
   2. BThe bonds are ionic, with charge shared equally around the ring
   3. CThe molecule is not three alternating single and double bonds, but a single delocalised system
   4. DBenzene contains six double bonds, one between each pair of carbons
   5. EThe carbon atoms are of two different kinds, alternating around the ring
