SOLVED: Silver nitrate in ethanol:AgNO3 is soluble in ethanol. The polar protic solvent promotes Sn1 reactions. Nitrate ion is not a good nucleophile, so it doesn't compete with iodide. The solvent favors ionization of the alkyl halide, promoting formation of a carbocation. AgCl and AgBr are insoluble in the solvent. This drives the reaction by forming a precipitate that can be used to monitor the reaction rate: Ag R-Cl R' AgCl (s)Ag R-BrROAgBr (s)

For an Na^ -Cl^- ion pair, attractive and repulsive energies EA and ER, respectively, depend on the distance between the ions r according to EA=-(1.436)/(r) ER=(7.32 × 10^-6)/(r^8) For these expressions, energies are expressed in electron volts per Na^ -Cl^- pair, and r is the distance in nanometers. The net energy EN is just the sum of the two expressions above. (a) Superimpose on a single plot EN, ER, and EA versus r up to 1.0 nm (b) On the basis of this plot, determine (i) the equilib
