Explanation

enzene is much more stable than expected. The extra stability means that benzene will less readily undergo addition reactions. In benzene, the π-electrons are delocalised and makes the structure more stable. Thus, benzene does not give addition reactions because of resonance stabilisation. The more loosely held electrons are open to attack by electrophiles. Hence, the characteristic reaction of benzene is electrophilic substitution. Example: Nitration and Suphonation of Benzene. So it does not undergo Elimination reaction.
