Benzene exhibits resonance. Resonance is a phenomenon in which electrons move between different possible locations within a molecule, resulting in the stabilization of the molecule. In benzene, the carbon atoms are arranged in a ring with alternating double bonds and single bonds. The electrons in the double bonds are delocalized and move freely around the ring, resulting in a more stable molecule. This is an example of resonance. The other molecules listed do not have a similar arrangement and therefore do not exhibit resonance.
