Eric V. Anslyn (born June 9, 1960, Santa Monica, California) is an American chemist , University Distinguished Teaching Professor, and Welch Regents Chair in Chemistry at the University of Texas at Austin. [1] He previously held the Norman Hackerman Professorship [citation needed]. Anslyn is co-author of Modern Physical Organic Chemistry, an ...
Benson group-increment theory (BGIT), group-increment theory, or Benson group additivity uses the experimentally calculated heat of formation for individual groups of atoms to calculate the entire heat of formation for a molecule under investigation.
Physical organic chemistry is the study of the relationship between structure and reactivity of organic molecules.More specifically, physical organic chemistry applies the experimental tools of physical chemistry to the study of the structure of organic molecules and provides a theoretical framework that interprets how structure influences both mechanisms and rates of organic reactions.
In supramolecular chemistry, [1] host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent ...
A non-bonding orbital, also known as non-bonding molecular orbital (NBMO), is a molecular orbital whose occupation by electrons neither increases nor decreases the bond order between the involved atoms.
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]
Both conformations are free of torsional strain, but, in the gauche conformation, the two methyl groups are in closer proximity than the sum of their van der Waals radii. The interaction between the two methyl groups is repulsive ( van der Waals strain ), and an energy barrier results.
Methanediol, also known as formaldehyde monohydrate or methylene glycol, is an organic compound with chemical formula CH 2 (OH) 2.It is the simplest geminal diol.In aqueous solutions it coexists with oligomers (short polymers).
