Physical organic chemistry

enforced concerted mechanism

Chemistry; Physical organic chemistry

Variation of reaction parameters in a series of reactions proceeding in non-concerted steps may lead to a situation, where the putative intermediate will possess a lifetime shorter than a bond ...

entering group

Chemistry; Physical organic chemistry

An atom or group that forms a bond to what is considered to be the main part of the substrate during a reaction. For example: the attacking nucleophile in a bimolecular nucleophilic substitution ...

enthalpy of activation

Chemistry; Physical organic chemistry

The standard enthalpy difference between the transition state and the ground state of the reactants at the same temperature and pressure. It is related to the temperature coefficient of the rate ...

standard entalpy of activation

Chemistry; Physical organic chemistry

The standard enthalpy difference between the transition state and the ground state of the reactants at the same temperature and pressure. It is related to the temperature coefficient of the rate ...

entropy of activation

Chemistry; Physical organic chemistry

The standard entropy difference between the transition state and the ground state of the reactants, at the same temperature and pressure. It is related to the Gibbs energy of activation and enthalpy ...
