Unformatted text preview: ultraviolet-visible absorption band. CH 3 CH 2 CCH 3 O CH 2 =CH-CHCH 3 OH I II max = 275 nm, = 25 I II max < 200 nm, = 12,000 (B) Match the correct structure in each pair below with the ultraviolet absorption data. (C) Compound A shows an intense absorption in the visible at 450 nm. A pure sample of A in ethanol (1.00 x 10-5 M ) has an Absorbance = 1.00 when measured in a 1.00-cm cell. What is the molar extinction coefficient at 450 nm? 450 = (4) Draw the structure of the most stable intermediate in the addition of Br 2 to 1,3-pentadiene, and the two products produced....
