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
principle of least nuclear motion
Chemistry; Physical organic chemistry
The hypothesis that, for given reactants, the reactions involving the smallest change in nuclear positions will have the lowest energy of activation . (It is also often simply referred to as ...
principle of microscopic reversibility
Chemistry; Physical organic chemistry
In a reversible reaction, the mechanism in one direction is exactly the reverse of the mechanism in the other direction. This does not apply to reactions that begin with a photochemical excitation.
principle of nonperfect synchronization
Chemistry; Physical organic chemistry
This principle applies to reactions in which there is a lack of synchronization between bond formation or bond rupture and other primitive changes that affect the stability of products and reactants, ...
product development control
Chemistry; Physical organic chemistry
The term is used for reactions under kinetic control where the selectivity parallels the relative (thermodynamic) stabilities of the products. Product development control is usually associated with a ...
product-determining step
Chemistry; Physical organic chemistry
The step of a stepwise reaction, in which the product distribution is determined. The product-determining step may be identical to, or occur later than, the rate-controlling step on the reaction ...
protogenic (solvent)
Chemistry; Physical organic chemistry
Capable of acting as a proton (hydron) donor strongly or weakly acidic (as a Brønsted acid). The term is preferred to the synonym "protic" or the more ambiguous expression "acidic" by itself. Also ...
proton affinity
Chemistry; Physical organic chemistry
The negative of the enthalpy change in the gas phase reaction (real or hypothetical) between a proton (more appropriately hydron) and the chemical species concerned, usually an electrically neutral ...
