Question #40
Step by step
Solved in 2 steps
- Complete the reaction: 42K19 → + β + [a]_____________(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…Write equations for the reaction of 2-butanol with reagent. Where you predict no reaction, write NR. Q)K2Cr2O7, H2SO4, H2O, heat
- Write equations for the reaction of 1-butanol with reagent. Where you predict no reaction, write NR. Q) K2Cr2O7, H2SO4, H2O, heatI have this task in organic chemistry (book: Brown's introduction to organic chemisty, global edition). Task 10:42. In (a) I have to tell what the funcion of K2CO3 is in step 1. Is it that CO32- take the hydrogen atom in 1-napthol? Will it then be a SN2 mechanism? In (b) I have to name the amine used in step 2 to form Propanolol. But I can't really find out how to come up with an amine that will make that reaction. Here are two pictures of the task:In the lab for the synthesis of methyl m-nitrobenzoate from methyl benzoate using HNO3 and H2SO4 via EAS, the product is recrystallized to remove impurities using 95% ethanol. Would o-nitrobenzoate and methyl p-nitrobenzoate be considered impurities? If that is so, how come ethanol can remove o-nitrobenzoate and methyl p-nitrobenzoate, but has no effect on m-nitrobenzoate? Thank you.
- 57. What are the nucleophile and electrophile in the cyclization of glucose below?(10pts) Compound A, C10H16, was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, CioH2o. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid (CHCOOH). The other fragment, compound C, was an optically active carboxylic acid, C8H14O2. Write reactions, and draw the correct structures for A-C, explain your answer in detail.Chemistry Please answer the following two questions. 1.)
