pH is water based phenomenon due to dissociation of H2O molecules into H+ and OH- ions, this concept being called as ionic product of water. Benzene is an organic molecule and does not dissociate into H+ ions, hence its pH can not be measured and told.
If we really want to check pH od benzene, then we can mix benzene with neutral water [pH 7] , separate the benzene layer away and check the pH of water layer. Most probably it will be 7.
