The resonance contributing structure of the thymine is to be drawn. The evidence that supports the statement that the thymine follows the Hückel’s rule is to be explained. Concept introduction: A molecule that is cyclic, planar, completely conjugated and follows Huckel’s rule is classified as an aromatic compound. Aromatic compounds follow Huckel’s rule of ( 4 n + 2 ) π electrons. A ring that contains six or ten π electrons acts as an aromatic ring. The stability of a compound depends upon the number of resonating structures.
