Physical organic chemistry

Swain-Lupton equation

Chemistry; Physical organic chemistry

A dual parameter approach to the correlation analysis of substituent effects, which involves a field constant (F) and a resonance constant (R). The original treatment was modified later. The ...

Tautomerization

Chemistry; Physical organic chemistry

The isomerization by which tautomers are interconverted. It is a heterolytic molecular re-arrangement and is frequently very rapid.

Termination

Chemistry; Physical organic chemistry

The steps in a chain reaction in which reactive intermediates are destroyed or rendered inactive, thus ending the chain.

Symproportionation

Chemistry; Physical organic chemistry

Synonymous with comproportionation.

Rho-value

Chemistry; Physical organic chemistry

A measure of the susceptibility to the influence of substituent groups on the rate constant or equilibrium constant of a particular organic reaction involving a family of related substrates. Defined ...

ρ-value

Chemistry; Physical organic chemistry

Sigma constant

Chemistry; Physical organic chemistry

Specifically the substituent constant for meta- and for para-substituents in benzene derivatives as defined by Hammett on the basis of the ionisation constant of a substituted benzoic acid in water ...
