Tiyoofene waa xeryahooda heterocyclic leh caanaha C4H4S. Waxay ka kooban tahay giraan shan xubnood leh, waa mid udgoon sida lagu tilmaamay falcelinta beddelidda ballaaran. Waa dareere aan midab lahayn oo leh ur u eg benzene. Inta badan falcelinta, waxay u egtahay benzene. Xidhiidhada la midka ah ee thiophene waxaa ka mid ah furan (C4H4O) selenophene (C4H4Se) iyo pyrrole (C4H4NH), kuwaas oo mid walba ku kala duwan yahay heteroatom ee giraanta. Su'aal: Waa maxay xarunta C4H4S?
