A guy named Benjamin Zene. Just kidding. The substance was known to European and Asian alchemists as early as the 15th century, but it was actually Michael Faraday who first isolated it and did the first meaningful experiments with it, and that was in the 1820's.
The person that "invented" benzene is Michael Faraday, when he "isolated" and "identified" benzene in 1825, from an oily residue derived from the production of illuminating gas.

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.
Polyphenols are determined by a benzene ring containing a carbolic acid (-OH) group. This will be bonded to the ring with an sp hybridized carbon.
Meso-stilbene dibromide is an organic molecule. Its structure is a benzene ring bonded to a carbon with a hydrogen and a bromine. That carbon is bonded to another carbon with a bromine that is ANTI to the first bromine. This carbon is then also bonded to a benzene ring.
Carbazole is an aromatic heterocyclic organic compound. It has a tricyclic structure, consisting of two six-membered benzene ring fused on either side of a five-membered nitrogen-containing ring.
Huckel's rule does not explain the structure of a molecules it simply describes that a molecule is aromatic or not, the kekule's structure for benzene agrees with Huckel's rule.
The structure of benzene.
There are 2 resonance structures for benzene.
A benzobarrelene is any hydrocarbon whose structure is that of a benzene ring fused with a double bond of barrelene.

Benzene has the structure C6H6 so should have double bonds but it does not instead it has a unsaturated electron above or below it. This is also known as an area of high electron density.
Benzene has a property called resonance. Because of this, the three pi-bonds in benzene act as a rather delocalized single pi-structure. So, benzene does not actually have 3 distinct pi-bonds. This pi-structure is stable, which explains why benzene is more stable than it would be if it had 3 pi-bonds.
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.
Now this is a benzene ring with a Hydroxide on top, and a bromide on bottom; the p means opposite side

Benzene, C6H6, as shown on the left, is an organic aromatic compound with many interesting properties. Unlike aliphatic (straight chain carbons) or other cyclic organic compounds, the structure of benzene (3 conjugated π bonds) allows benzene and its derived products to be useful in fields such as health, laboratorial, and other applications such as rubber synthesis.
