The brand new understanding of benzene, and therefore of all aromatic compounds, proved to generally be so significant for both equally pure and applied chemistry that in 1890 the German Chemical Society organized an elaborate appreciation in Kekulé's honor, celebrating the twenty-fifth anniversary of his initially benzene paper. in this article Kekulé spoke in the creation of the idea. He mentioned that he had found the ring form from the benzene molecule after getting a reverie or day-desire of a snake biting its have tail (a symbol in historic cultures referred to as the ouroboros).[39] This vision, he claimed, came to him after several years of learning the character of carbon-carbon bonds. This was seven several years right after he had solved the challenge of how carbon atoms could bond to up to 4 other atoms at the same time.
