Benzene is more acidic than n-hexane. Acidity refers to the donation of H+ ions. If the conjugate base formed is stable, then the species is more acidic. When the H+ ions are ejected from the benzene ring, there is a negative charge on the benzene ring, which is stabalised by the resonance effect. due to the formation of it's resonating structures. While, in n-hexane there will only be the +I effect of the alkyl group. Since, the resonance effect is more powerful than the inductive effect, hence benzene ring is more stable than n-hexane.

look the as the s-shrecter of the hybrid orbitals increases Electronegetivity increases.......and hence the acidity increases... now benzene has sp2 hybrd orbitals...while n-hexane has sp3 hybrd orbitals....so beneze is more acidic
