    Benzene is an aromatic compound. It has a 36 kcal/mole stabilization over a non aromatic compound. This means it takes too much energy to break the aromaticity and undergo addition. The aromaticity is due to cyclic conjugation of Pi bonds within the structure.

    However, it should be noted that under the right conditions, benzene can undergo nucleophilic addition followed by elimination.
