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

isotopologue

Chemistry; Physical organic chemistry

A molecular entity that differs only in isotopic composition (number of isotopic substitutions), e.g. CH 4 , CH 3 D, CH 2 D 2 ... .

isotopomer

Chemistry; Physical organic chemistry

Isomers having the same number of each isotopic atom but differing in their positions. The term is a contraction of "isotopic isomer". Isotopomers can be either constitutional isomers (e.g. CH 2 ...

Kamlet-Taft solvent parameters

Chemistry; Physical organic chemistry

Parameters of the Kamlet-Taft solvatochromic relationship which measure separately the hydrogen bond donor (α), hydrogen bond acceptor (β), and dipolarity/polarizability (π*) properties of solvents ...

kinetic control of product composition

Chemistry; Physical organic chemistry

The term characterizes conditions (including reaction times) that lead to reaction products in a proportion governed by the relative rates of the parallel (forward) reactions in which the products ...

kinetic electrolyte effect

Chemistry; Physical organic chemistry

The general effect of an added electrolyte (i.e. an effect other than, or in addition to, that due to its possible involvement as a reactant or catalyst) on the observed rate constant of a reaction ...

Koppel-Palm solvent parameters

Chemistry; Physical organic chemistry

Parameters to measure separately the ability of a solvent to enter into non-specific solvent-solute interactions (permittivity ε and refractive index n D ) and specific solvent-solute interaction ...

labile

Chemistry; Physical organic chemistry

The term has loosely been used to describe a relatively unstable and transient chemical species or (less commonly) a relatively stable but reactive species. It must therefore not be used without ...
