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. 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. impasto in english
