The number of Kekult structures for primitive coronoids is studied. The systems have obvious counterparts within a class of hydrocarbons known as cycloarenes. Complete solutions are given for centrosymmetrical primitive coronoids and those with trigonal or hexagonal symmetries. The technique is base
