In the first stage of the Hock process, this molecule is alkylated with propylene to form cumene. This compound is the lightest in a mixture produced through the catalytic reforming of naphtha called BTX. A methylated derivative of this compound is nitrated three times to produce TNT. (-5[1])A different (-5[1])derivative (-5[1])of this compound with two methyl substituents may be (10[1])prefixed ortho-, meta-, or para- and is called xylene. Each carbon-carbon bond in this compound has a bond order of 1.5 due to the delocalization of its six pi electrons.
