WebThe sixth bonding interaction is made possible by benzene's p orbitals being in a ring. Because benzene's pi 1 molecular orbital has more stabilizing bonding interactions it is lower in energy than the pi 1 molecular orbital of 1,3,5-hexatriene. This gives benzene the additional aromatic stability not seen in the acyclic 1,3,5-hexatriene. WebAlmost all styrene is now produced by dehydrogenation of ethylbenzene, a compound obtained by reacting ethylene and benzene —both of which in turn are derived from petroleum. More than 15 million metric tons of the liquid are made each year.
