Physical organic chemistry

Onium ion

Chemistry; Physical organic chemistry

(1) A cation (with its counterion) derived by addition of a hydron to a mononuclear parent hydride of the nitrogen, chalcogen and halogen family, e.g. H 4 N + ammonium ion. (2) Derivatives formed by ...

Outer-sphere (electron transfer)

Chemistry; Physical organic chemistry

An outer-sphere electron transfer is a reaction in which the electron transfer takes place with no or very weak (4 -16 kJ mol -1 ) electronic interaction between the reactants in the transition ...

Oxidative coupling

Chemistry; Physical organic chemistry

The coupling of two molecular entities through an oxidative process, usually catalysed by a transition metal compound and involving dioxygen as the oxidant; e.g., 2 CO + 2 MeOH + 1/2 O 2 (+ ...

Optical yield

Chemistry; Physical organic chemistry

In a chemical reaction involving chiral reactants and products, the ratio of the optical purity of the product to that of the precursor, reactant or catalyst. This should not be confused with ...

Orbital steering

Chemistry; Physical organic chemistry

A concept expressing that the stereochemistry of approach of two reacting species is governed by the most favourable overlap of their appropriate orbitals.

Reactive

Chemistry; Physical organic chemistry

As applied to a chemical species, the term expresses a kinetic property. A species is said to be more reactive or to have a higher reactivity in some given context than some other (reference) species ...
