acids AND bases - 2025 Penn Bowl

Question

In one model, a parameter symbolized W represents the energy needed to cleave these two classes of compounds. For 10 points each:

[10m] Name these two classes of compounds described by Drago and Wayland’s ECW model. Another theory describes these two types of compounds based on quantities like polarizability, oxidation state, and atomic radius.

ANSWER: acids AND bases [accept answers in either order; accept Lewis acids AND Lewis bases; accept hard or soft acids AND bases; prompt on HSAB]

[10e] The ECW model can be used to predict this quantity for an acid-base reaction. This thermodynamic quantity equals the sum of internal energy and pressure times volume, and is symbolized H.

ANSWER: enthalpy [reject “entropy”]

[10h] Hard-soft acid-base theory supports the theory behind this rule, which states that SN1 reactions will happen at more electronegative atoms of an ambident nucleophile, and SN2 reactions will occur at less electronegative atoms.

ANSWER: Kornblum’s rule
