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
diastereoisomerism
Chemistry; Physical organic chemistry
Stereoisomerism other than enantiomerism. Diastereoisomers (or diastereomers) are stereoisomers not related as mirror images. Diastereoisomers are characterized by differences in physical properties, ...
dielectric constant
Chemistry; Physical organic chemistry
A measure for the effect of a medium on the potential energy of interaction between two charges. It is measured by comparing the capacity of a capacitor with and without the sample present.
dimerization
Chemistry; Physical organic chemistry
The transformation of a molecular entity A to give a molecular entity A 2 . For example: CH 3 . + H 3 C . → CH 3 CH 3 2 CH 3 COCH 3 → (CH 3 ) 2 C(OH)CH 2 COCH 3 2 RCOOH → (RCOOH) 2
dipolar aprotic solvent
Chemistry; Physical organic chemistry
A solvent with a comparatively high relative permittivity (or dielectric constant), greater than ca. 15, and a sizable permanent dipole moment, that cannot donate suitably labile hydrogen atoms to ...
dipolar bond
Chemistry; Physical organic chemistry
A bond formed (actually or conceptually) by coordination of two neutral moieties, the combination of which results in charge-separated structures, e.g., R 3 N: + O → R 3 N + -O - The term is ...
dipole-dipole interaction
Chemistry; Physical organic chemistry
Intermolecular or intramolecular interaction between molecules or groups having a permanent electric dipole moment. The strength of the interaction depends on the distance and relative orientation of ...
