Kekule, August structural theory

From the concept of isomerism we can trace the origins of the structural theory—the idea that a precise arrangement of atoms uniquely defines a substance Ammonium cyanate and urea are different compounds because they have different structures To some degree the structural theory was an idea whose time had come Three scientists stand out however for independently proposing the elements of the structural theory August Kekule Archibald S Couper and Alexander M Butlerov... 

In 1866 only a few years after publishing his ideas concerning what we now rec ognize as the structural theory of organic chemistry August Kekule applied it to the structure of benzene He based his reasoning on three premises... 

In 1866, August Kekule used the principles of structural theory to postulate a structure for the benzene molecule. Kekule based his postulation on the following premises ... 

August Kekule (1829-1892) is well known as one of the pioneers of modern structural theory in organic chemistry. He became interested in chemistry after attending classes of Justus von Liebig, then went to study in Paris with Charles Gerhardt, and became acquainted with Jean-Baptiste Dumas. He enrolled in the University of Heidelberg as a Privatdozent in 1856, then in the...

Between 1858-1861, August Kekule, Archibald Scott Couper and Alexander M. Butlerov independently established one of the fundamental theories in organic chemistry The Structural Theory of Organic Compounds . 

One of the preeminent creators of structural theory was August Kekule, probably best known for advancing the hexagonal structure for benzene, C Hg. Any structural formula for benzene had ultimately to take account of the following facts the well-established quadrivalency of carbon the complete equivalence of benzene s six... 

Rede von August Kekul6," in Schultz, "Bericht," 1302-11 reprinted in Anschutz, 1 937-47. A nearly complete English translation was published by O. T. Benfey, "August Kekule and the Birth of the Structural Theory" (1958). 

In 1866, August Kekul used his recently published structural theory of matter to propose a structure for benzene. Specifically, he proposed a ring comprised of alternating double and single bonds.
