As benzene has the molecular formula C6H6, you would assume its structure would be cyclohexa-1,3,5-triene as carbon forms 4 bonds. Benzene is more stable as it is less exothermic than cyclohexa-1,3,5-triene so more energy is taken in compared to cyclohexa-1,3,5-triene.

Benzene (C6H6) has six C-atoms and six H-atoms, it contains three double bonds alternately between two C-atoms. Cyclohexane (C6H12) has six C-atoms each possessing two H-atoms, thus twelve H-atoms total. It does not consist any double bond.

As nouns the difference between benzene and hexane is that benzene is benzene (aromatic compound) while hexane is (organic compound) any of five isomeric aliphatic hydrocarbons, c6h14 they are colorless, volatile liquids.

There are 3 pi bonds in benzene. Pi bonds are weaker than sigma bonds. Therefore,benzene easily takes part in reaction. Hence, cyclohexane is more stable than benzene.

All of the carbon-carbon bonds have exactly the same lengths – somewhere between single and double bonds. There are delocalized electrons above and below the plane of the ring, which makes benzene particularly stable. Why benzene is not 1,3,5-cyclohexatriene.

The primary difference between benzene and the fictional compound 1,3,5-cyclohexatriene is the bond length. Cyclohexatriene has alternating single and double bonds, and one would expect that the double bonds would be significantly shorter than the single bonds. In benzene, however, all of the bonds are the same length.

12 sigma bonds

There are 2 pi bonds and 4 sigma bonds.
