3. Degree of unsaturation - Wikipedia

   en.wikipedia.org/wiki/Degree_of_unsaturation

   In the analysis of the molecular formula of organic molecules, the degree of unsaturation (DU) (also known as the index of hydrogen deficiency (IHD), double bond equivalents (DBE), or unsaturation index [1]) is a calculation that determines the total number of rings and π bonds. A formula is used in organic chemistry to

4. Taft equation - Wikipedia

   en.wikipedia.org/wiki/Taft_equation

   The Taft equation is a linear free energy relationship (LFER) used in physical organic chemistry in the study of reaction mechanisms and in the development of quantitative structure–activity relationships for organic compounds. It was developed by Robert W. Taft in 1952 [2] [3] [4] as a modification to the Hammett equation. [5]

   A 1,2-diamino-diol is then formed after proton exchange and a nucleophilic attack of water to the former nitrile carbon. Ammonia is subsequently eliminated after the protonation of the amino group, and finally the deprotonation of a hydroxyl group produces an amino acid .

6. Grunwald–Winstein equation - Wikipedia

   en.wikipedia.org/wiki/Grunwald–Winstein_equation

   In physical organic chemistry, the Grunwald–Winstein equation is a linear free energy relationship between relative rate constants and the ionizing power of various solvent systems, describing the effect of solvent as nucleophile on different substrates. The equation, which was developed by Ernest Grunwald and Saul Winstein in 1948, could be ...

7. Enantiomeric excess - Wikipedia

   en.wikipedia.org/wiki/Enantiomeric_excess

   the specific rotation of enantiopure 1-phenylethanol can be enhanced by the addition of achiral acetophenone as an impurity. [ 4 ] The term enantiomeric excess was introduced in 1971 by Morrison and Mosher in their publication Asymmetric Organic Reactions . [ 5 ]
