Nothing, they don't react with each other.
Benzene is an organic molecule made up of six carbon atoms connected to form a ring. This is called the benzene ring. The benzene ring structure occures in several other, more complex, organic moleculed.

Benzaldehyde has the formula C7H6O, it has the carbonyl carbon of the aldehyde bound to a benzene ring. You can't have a =O unit bound directly to the benzene ring because you would have a carbon with five bonds.
Phenols are acidic in aqueous solution. The oxygen atom off of the benzene ring acts as an electron donating group, and pulls the electron density towards the benzene ring and away from the hydrogen atom. This makes the hydrogen easily extracted by free floating H2O molecules. Because of this, H3O+ molecules form, and this is equivalent to H+ which can show a low pH, which is characteristic of acidic solutions.
Hi ,As you know from the structures of both the compounds that toluene has a methyl group on the benzene ring which is electron releasing group and hence activate the benzene ring by pushing the elctrons on the benzene ring. On the other hand nitro group on the benzene ring is electron withdrawing group which deactivates the benzene ring by withdrawing the electrons from the benzene ring . Now in the nitration attack of the nucleophile ( NO2 +) takes place. Hence reaction will takes place on that benzene faster which have more electron density on its ring which is the case of toluene.
A ring is a cyclic molecule as benzene.
There are 2 resonance structures for benzene.
They are all homologues that contain a benzene ring

Phenol is activated by the OH group, which means it is more readily brominated than benzene. The OH group has an electron supplying effect, the ring is then more electron rich. The lone pair from the oxygen atom is interacting with the ring electrons, thus making the ring more attractive to electrophiles (the electrophile here being Brdelta+) . Compare this with brominating a plain benzene ring where you would need a halogen carrier (Friedel-Crafts type) to generate a strong enough electrophile. It undergoes trisubstitution because phenol is so readily brominated and the bromine goes onto the activated positions on the ring (2,4,6) Hope this is enough information Marie
