- Please draw the reaction (attached)and explain the mechanism of an SN2 reaction then identify the nucleophile, substrate and the leaving group.Plastic photochromic sunglasses are based on the following reversible rearrangement of a dye inside the lenses that occurs when the lenses are exposed to sunlight. The original dye absorbs UV light but not visible light and is thus colorless, while the rearrangement product absorbs visible light and is thus darkened. (a) Show the mechanism of the rearrangement. (b) Why does the rearrangement product absorb at a longer wavelength (visible light) than the original dye (UV)?Benzvl chloride can be converted into benzaldehvde by treatment with nitromethane and base. The reaction involves initial conversion of nitromethane into its anion, followed by SN2 reaction of the anion with benzyl chloride and subsequent Ε2 reaction. Write the mechanism in detail, using curved arrows to indicate the electron flow in each step.
