WebFor example, hexane, C 6 H 14, loses hydrogen and turns into benzene. As long as you draw the hexane bent into a circle, it is easy to see what is happening. Similarly, methylbenzene (toluene) is made from heptane: The process. The feedstock. The feedstock is a mixture of the naphtha or gasoline fractions and hydrogen. WebDifferent R groups on the phenyl group allows different benzene derivatives to be formed. Phenol, Ph-OH, or C 6 H 5 OH, for example, is formed when an alcohol (-OH) group displaces a hydrogen atom on the benzene ring. Benzene, for this very same reason, can be formed from the phenyl group by reattaching the hydrogen back its place of removal.

"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. " - How is benzene created
