5. Optically pure 2-octyl sulfonate was treated with varying mixtures of water and dioxane, and the optical purity of the resulting product (2-octanol) was found to vary with the ratio of water to dioxane, as shown in the following table (J. Am. Chem. Soc. 1965, 87, 287-291). Given that dioxane possesses fairly nucleophilic oxygen atoms, provide a complete mechanism that explains the variation in in the product's optical purity due to changes in solvent composition. Hint, the solvent is doing more here than just dissolving. it is partaking in the reaction. Solvent Ratio (water : dioxane). 25:75 50: 50 75: 25 100:0 Optical purity of (S)-2-octanol. 77% 88% 95% 100% H20 OH (R)-2-0ctyl sulfonate (optically pure) (S)2-Octanol (dioane)

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or  ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.
