Dual substituent-parameter equation

Chemistry; Physical organic chemistry

In a general sense, this is any equation which expresses substituent effects in terms of two parameters. However, in practise the term is used more specifically for an equation for summarising the ...

Disproportionation

Chemistry; Physical organic chemistry

Any chemical reaction of the type A + A → A' + A", where A, A' and A" are different chemical species. For example: 2 ArH + → ArH + ArH 2+ The reverse of disproportionation is called ...

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 ...

Dissociation

Chemistry; Physical organic chemistry

(1) The separation of a molecular entity into two or more molecular entities (or any similar separation within a polyatomic molecular entity). Examples include unimolecular heterolysis and homolysis, ...

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 ...
