A molecular of benzene has :

The molecular mass of benzene is 78 and its percentage composition is 92.3 C and 7.69 H. Determine the molecular formula of benzene?

According to the molecular formula, benzene appears to be highly unsaturated. But bezene mainly participates in substitution reactions. It is because benzene is
