Practice Problems 3. Explain why 4-methyl-3-penten-2-one absorbs at 314 nm, quite a bit higher than both butadiene and hexatriene. Your answer must explain how Lmax relates to molecular structure. 4. Explain which reaction would be faster and why. You need to use the rate law data to recognize which mechanism is at play. Br Nal Reaction 1: acetone substrate A Rate = k [substrate A] Nal Reaction 2: acetone Br Br substrate B Rate = k [substrate B]

please explain why the circled answer choice is correct.
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)?
pls answer both :) thank u
