The formula of benzene is C6H6.

• Benzene consists of a ring of six carbon atoms, each bonded to one hydrogen atom.

• The molecular formula for benzene is C6H6.

• The structural formula of benzene is represented as a hexagon with alternating double bonds.

Toluene can be prepared by the catalytic reforming of petroleum naphtha.

• Toluene is commonly produced by the catalytic reforming of petroleum naphtha.

• The process involves heating the naphtha to high temperatures in the presence of a catalyst.

• The resulting mixture is then distilled to separate out the toluene.

• Another method involves the methylation of benzene using methanol in the presence of a catalyst.
