In the Hansch equation, the desired concentration of a drug is expressed in terms of the solubility of the drug, the sensitivity of the reaction to electron density, and THIS factor, and the delta term in the Taft equation describes an equivalent property. For a homonuclear molecule, it can be expressed as one minus cosine gamma, where two gamma is the opening angle of the cone of acceptance for the reaction. This property is unusually above unity in harpoon reactions. I
In the Hansch equation, the desired concentration of a drug is expressed in terms of the solubility of the drug, the sensitivity of the reaction to electron density, and THIS factor, and the delta term in the Taft equation describes an equivalent property. For a homonuclear molecule, it can be expressed as one minus cosine gamma, where two gamma is the opening angle of the cone of acceptance for the reaction. This property is unusually above unity in harpoon reactions. It approximately represents the ratio of the collisional cross section to the total cross section, and the pre-exponential factor of the Arrhenius equation is the product of this value and the collision frequency. The value of this term is increased by catalysts that orient reactants to promote product formation. For 10 points, name this term from collision theory that describes the probability that molecules will collide in the correct orientation and position for the reaction to proceed as desired.
