The color we perceive from the dye is a result of its interaction with light. Red dye transmits red light, and absorbs other colors of light. Consider the absorption spectrum of Red #40, below. Absorbance spectrum of Red #40 425 450 500 Absorbance 550 0.9 0.7 0.5 Which wavelength is most absorbed by the Red #40 dye? 0.3 0.1 -0.1 400 450 500 550 600 650 Wavelength (nm)

(A true story.) A drug user responded to an ad placed by a DEA informant in a drug-culture magazine. He later flew fromColorado to Maryland, where he bought some 1-phenyl-2-propanone (P2P) from the informant. The police waited nearlya month for the suspect to synthesize something, then obtained a search warrant, and searched the residence. They foundthe unopened bottle of P2P; apparently, the suspect was not a good chemist and was unable to follow the instructions theinformant gave him. They also found pipes and bongs with residues of marijuana and cocaine, plus a bottle of methylamine hydrochloride, some muriatic acid (dilute HCl), zinc strips, flasks, and other equipment.(a) Assume you are consulting for the police. Show what synthesis the suspect was prepared to carry out, to provideprobable cause for the charge of attempting to manufacture a controlled substance.(b) Assume you are a member of the jury. Would you convict the defendant of attempting to manufacture a…
