Physical organic chemistry

Physical organic chemistry

Physical organic chemistry is the study of the interrelationships between structure and reactivity in organic molecules. It a part of organic chemistry by using tools of physical chemistry such as chemical equilibrium, chemical kinetics, thermochemistry, and quantum chemistry.

Physical organic chemistry

proton transfer reaction

Chemistry; Physical organic chemistry

A chemical reaction, the main feature of which is the intermolecular or intramolecular transfer of a proton (hydron) from one binding site to another. For example, CH 3 CO 2 H + (CH 3 ) 2 C=O → ...

protophilic (solvent)

Chemistry; Physical organic chemistry

Capable of acting as proton acceptor, strongly or weakly basic (as a Brønsted base). Also called hydrogen bond acceptor (HBA) solvent.

pseudo-catalysis

Chemistry; Physical organic chemistry

If an acid or base is present in nearly constant concentration throughout a reaction in solution (owing to buffering or the use of a large excess), it may be found to increase the rate of that ...

quantitative structure-activity relationships (QSAR)

Chemistry; Physical organic chemistry

The building of structure-biological activity models by using regression analysis with physicochemical constants, indicator variables or theoretical calculations. The term has been extended by some ...

radical

Chemistry; Physical organic chemistry

A molecular entity such as . CH 3 , . SnH 3 , Cl . possessing an unpaired electron. (In these formulae the dot, symbolizing the unpaired electron, should be placed so as to indicate the atom of ...

free radical

Chemistry; Physical organic chemistry

A molecular entity such as . CH 3 , . SnH 3 , Cl . possessing an unpaired electron. (In these formulae the dot, symbolizing the unpaired electron, should be placed so as to indicate the atom of ...

radical center

Chemistry; Physical organic chemistry

The atom (or group of atoms) in a polyatomic radical on which an unpaired electron is largely localized. Attachment of a monovalent atom to a radical center gives a molecule for which it is possible ...
