14Alkane stereochemistry — concerns the stereochemistry of linear alkanes and the linear alkane conformers. The existence of more than one conformation is due to hindered rotation around sp3 hybridised carbon carbon bonds. The smallest molecule with such a chemical bond,… …
15Curtin–Hammett principle — The Curtin–Hammett principle is a principle in chemical kinetics proposed by David Yarrow Curtin and Louis Plack Hammett. It states that, for a reaction that has a pair of reactive intermediates or reactants that interconvert rapidly (as is… …
16Biochemistry of Alzheimer's disease — The biochemistry of Alzheimer s disease (AD), one of the most common causes of adult dementia, is as yet not well understood at the molecular level. It has been identified as a protein misfolding disease due to the accumulation of abnormally… …
17Computational chemistry — is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry, incorporated into efficient computer programs, to calculate the structures and properties of… …
18Rate equation — The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with concentrations or pressures of reactants and constant parameters (normally rate coefficients and partial reaction orders).[1] To determine the… …
19Barton, Sir Derek Harold Richard — ▪ 1999 British chemist (b. Sept. 8, 1918, Gravesend, Kent, Eng. d. March 16, 1998, College Station, Texas), altered the landscape of modern chemistry by originating the fields of conformational analysis and stereochemistry. He showed how… …
