Hofmann's chemical models. Artwork showing how early chemical models were used to demonstrate the formation of molecules,in this case methane (marsh-gas,CH4) and ethane (hydride of ethyl,C2H6). This demonstration was performed by the German chemist August Wilhelm von Hofmann (1818-1892) when he gave a lecture to the Royal Institution in London,England,on 7 April 1865. The title was 'On the Combining Power of Atoms',and these artworks were later published in the journal 'Proceedings of the Royal Institution' (volume 4,1866,pp.401-430) | |
