Linear Relationships between Thermodynamic Parameters (Part ) Critical Evaluation and Mechanistic Significances of the Relationship

[摘要] Justifications for the use of ¥ò and Y as independent potential energy variables in the general equation have been reviewed and some mechanistic significances of the relationship discussed. Analysis of the activation parameters for the solvolysis of benzyl chlorides in ethanol-water mixture showed that there are two distinct series of substrate constants a', which can be correlated linearly within a series with the substituent constants ¥ò conforming to the generally accepted concept of change in mechanism from SN1 to SN2.
