    Extractions: Kolbe's Criticism of van't Hoff In 1878 the 26 year-old Jacobus Henricus van't Hoff, who would receive the first Nobel Prize in Chemistry in 1901, was installed as the first Professor of Chemistry, Mineralogy, and Geology in the new University of Amsterdam. For the occasion he delivered an inaugural lecture entitled "Imagination in Science" [see translation by G. F. Springer, Springer-Verlag, 1967 from which the following extracts are adapted] . He began the address with a counter-example, quoting Hermann Kolbe who had shown such short-sightedness and intemperance in criticizing van't Hoff's most memorable work, first published when van't Hoff was 22; and Kolbe, 56. Kolbe was accustomed to using the journal he edited as a bully pulpit for keeping chemists on the intellectual straight and narrow. Kolbe wrote: I have recently published an article in , 288 ff.) giving as one of the reasons for the contemporary decline of chemical research in Germany the lack of well-rounded as well as thorough chemical education. Many of our chemistry professors labor with this problem to the great disadvantage of our science. As a consequence of this, there is an overgrowth of the weed of the seemingly learned and ingenious but in reality trivial and stupefying natural philosophy. This natural philosophy, which had been put aside by exact science, is at present being dragged out by pseudoscientists from the junk-room which harbors such failings of the human mind, and is dressed up in modern fashion and rouged freshly like a whore whom one tries to smuggle into good society where she does not belong.

    Extractions: by Dr. J. H. van't Hoff translated into German by Dr. F Herrmann (1877) Jacobus Henricus van't Hoff published the first 12-page version of this epochal pamphlet in Dutch when he was barely 22 . The original title was "Voorstel tot Uitbreiding der Tegenwoordige in de Scheikunde gebruikte Structuurformules in de Ruimte, benevens een daarmee samenhangende Opmerking omtrent het Verband tusschen Optisch Actief Vermogen en chemische Constitutie van Organische Verbindingen" (Proposal for the Extension of Current Chemical Structural Formulas into Space, together with Related Observation on the Connection between Optically Active Power and the Chemical Constitution of Organic Compounds), a descriptive but lengthy title for such a short pamphlet. It was translated into French in 1875 as "La chimie dans l'espace" (Chemistry in Space), but this 1877 German translation "Die Lagerung der Atome im Raume" was the most influential and controversial. He went on to found the discipline of physical chemistry and received the first Nobel Prize in Chemistry (1901). It recognized his contributions in physical chemistry, not in organic stereochemistry.

Van't Hoff's Nobel lecture was entitled " Osmotic Pressure and Chemical Equilibrium ." The essence of the paper deals with the mathmatical relationship between the osmotic pressure and chemical equilibrium (determining K from osmotic pressure), molecules in solutions being essentially the identical to their gaseous counterparts, the Van't Hoff factor i in relation to ionic molecules, as well as an elementary introduction to the concept of osmotic pressure in relation to gaseous (atm) pressure. His stereochemistry contributions (he is often refered to as the father of stereochemistry) are especially important in the details of an SN2 reaction. 2004 chemistry homework Notice: Microsoft has no responsibility for the content featured in this group.

    Extractions: see previous page Jacobus Henricus van 't Hoff August 30 March 1 ) was a Dutch physical and organic chemist , the winner of the first Nobel Prize in Chemistry He was born in Rotterdam , the son of a medical doctor. From a young age he was interested in science, and against the wishes of his father he went to study chemistry , first at the Delft Polytechnical Institute , then at the University of Leiden , then to Bonn Germany (where he studied with Friedrich Kekulé ), then Paris (where he studied with C. A. Wurtz), and finally receiving his doctorate at the University of Utrecht in Before receiving his doctorate, however, Van 't Hoff already published the first of his important contributions to organic chemistry . He accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed toward the corners of a regular tetrahedron . This three-dimensional structure perfectly accounted for the isomers found in nature. He shares credit for this idea with the

    Extractions: S.A. Arrhenius, 1924 Svante August Arrhenius was a Swedish physical chemist best known for his theory that electrolytes, certain substances that dissolve in water to yield a solution that conducts electricity, are separated, or dissociated, into electrically charged particles, or ions, even when there is no current flowing through the solution. In 1903 he was awarded the Nobel Prize for Chemistry. Arrhenius as a student In 1876 he entered the University of Uppsala, studying mathematics, chemistry and physics. The practical instruction in physics was not of the best, and in 1881 he went to Stockholm to work under Professor E. Edlund at the Academy of Sciences. Here, Arrhenius began by assisting Edlund in his work on electromotive force measurements in spark discharges but soon moved to an interest of his own. This resulted in his thesis (1884) " " (Investigations on the galvanic conductivity of electrolytes). From his results the author concluded that electrolytes, when dissolved in water, become to varying degrees split or dissociated into electrically opposite positive and negative ions. The degree to which this dissociation occurred depended above all on the nature of the substance and its concentration in the solution - being more developed the greater the dilution. The ions were supposed to be the carriers of the electric current, e.g. in electrolysis, but also of the chemical activity. The relation between the actual number of ions and their number at great dilution (when all the molecules were dissociated) gave a quantity of special interest ("activity constant").

    Extractions: , by Louis Bernard Guyton de Morveau, Antoine Laurent Lavoisier The Pharmacopoeia of the United States is published, establishing standard English and Latin names for drugs. In a published outline of a chemistry course, Stanislao Cannizzaro clarifies the calculation of atomic weights, then a highly contentious subject, using, in part, the long-neglected hypothesis put forward by Amedeo Avagadro in 1811. Friedrich August Kekule and Archibald Scott Couper recognize that carbon atoms have the ability to link to one another in chains. Archibald Scott Couper uses straight lines to indicate valence bonds in organic compounds, as is still the practice in most modern structural diagrams. Congress is held at Karlsruhe Technische Hochschule to discuss the feasibility of establishing a systematic and rational nomenclature for chemistry. The congress does not reach any conclusive results, but several key participants return home with Stanislao Cannizzaro's outline (1858), which ultimately convinces them of the validity of his scheme for calculating atomic weights. Friedrich Kekule, as well as others, including Josef Loschmidt, identifies the ring structure of benzene.

    Extractions: by Erica Flapan A solution of tartaric acid, a compound found in the "tartar" formed during the fermentation of wine, will rotate polarized light to the right . There is another form of tartaric acid, called racemic acid (from the Latin word for a bunch of grapes). It has the same chemical composition, but is optically inactive. In 1848, the chemist Louis Pasteur noticed that crystals of racemic acid had two forms, which were mirror images of each other. He separated the crystals by hand. The resulting solutions were now optically active , the one rotating polarized light to the right , the other to the left . Thus, racemic acid was a mixture of two optically active forms of tartaric acid. New Ambidextrous Universe , pp. 112-113.) A molecule which has two mirror-image forms is said to be chiral (from the ancient Greek word for 'hand'). Erica Flapan explains, in the last chapter of the book under review, why molecules of DNA tend to be chiral. This fact helps to explain why molecules produced by living things are typically chiral, while molecules produced by inanimate natural processes are not. The chirality of organic molecules often has significant consequences. In the late 1950s, the drug thalidomide was prescribed to treat morning-sickness in pregnant women. By the early 1960s, it became clear that the drug was responsible for producing horrible birth defects. It was not until about 1980 that it was understood that thalidomide is a "racemic" mixture of two mirror-image chiral molecules. It is one of these two molecules which relieves morning-sickness; the other induces birth defects.

The first of the Nobel Prizes was presented in 1901 according to instructions in his will. At his death he was one of the richest men in the world, he also felt it would be wrong to leave his fortune to relatives. "Inherited wealth is a misfortune which merely serves to dull man's faculties." Alfred Nobel 1901 Jacobus Henricus van't Hoff won the first Nobel Prize in chemistry for his work on the relationship of volume, pressure and temperature in gases which became known as van't Hoff's Law.
