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
ionizing power
Chemistry; Physical organic chemistry
A term to denote the tendency of a particular solvent to promote ionization of an uncharged or, less often, charged solute. The term has been used both in a kinetic and in a thermodynamic context.
isodesmic reaction
Chemistry; Physical organic chemistry
A reaction (actual or hypothetical) in which the types of bonds that are made in forming the products are the same as those which are broken in the reactants, e.g. PhCOOH + p-ClC 6 H 4 COO - → ...
isoelectronic
Chemistry; Physical organic chemistry
Two or more molecular entities are described as isoelectronic if they have the same number of valence electrons and the same structure, i.e. number and connectivity of atoms, but differ in some of ...
isoentropic
Chemistry; Physical organic chemistry
A reaction series is said to be isoentropic if the individual reactions of the series have the same standard entropy of activation.
isoequilibrium relationship
Chemistry; Physical organic chemistry
A relationship analogous to the isokinetic relationship but applied to equilibrium data. The equation defining the isoequilibrium temperature β is Δ r H - βΔ r S = constant where ΔH and ΔS are ...
isokinetic relationship
Chemistry; Physical organic chemistry
When a series of structurally related substrates undergo the same general reaction or when the reaction conditions for a single substrate are changed in a systematic way, the enthalpies and entropies ...
isolobal
Chemistry; Physical organic chemistry
The term is used to compare molecular fragments with each other and with familiar species from organic chemistry. Two fragments are isolobal if the number, symmetry properties, approximate energy, ...
