Aromatic



In chemistry, an aromatic molecule is one in which electrons are free to cycle around circular arrangements of atoms, which are alternately singly and doubly bonded to one another. (More properly, these bonds may be seen as a hybrid of a single bond and a double bond, each bond in the ring being identical to every other.) This commonly seen model of aromatic rings was developed by Friedrich August Kekulé von Stradonitz. The model for benzene consists of two resonant forms, which corresponds to the double and single bonds switching positions.
