Benzene
In 1986, some chemists disputed the delocalized view of benzene in an article published in the journal Nature. They showed that the electrons in benzene are almost certainly localized to particular carbon atoms. They showed the aromatic properties of benzene come from spin coupling rather than electron delocalization. Other scientists wrote articles to support this view in Nature in 1987. But, chemists are slow to switch from the delocalized electrons view.
