Concept explainers
Interpretation:
A reaction roadmap have to be made for the reactions in the study Guide section of chapter 7 with the help of the previous chapter question 6.54.
Concept Introduction:
Markonikov addition: The addition reaction of parotic acids to a different
Anti-Markonikov addition: These rules describe the regiochemistry where the substituent is bonded to a less substituted carbon, rather than the more substituted carbon. This placed is quite unusual as carbon cations which are commonly formed during alkene or alkyne reactions tend to favor the more substituted carbon.
Lindlar catalyst: The catalyst is used for the hydrogenation of

- Using your reaction roadmap as a guide, show how to convert butane into butanal. Show all reagents needed and all molecules synthesized along the way.arrow_forwardA newer generation of antipsychotics, among them clozapine, are now used to treat the symptoms of schizophrenia. These drugs are more effective than earlier drugs in improving patient response in the areas of social withdrawal, apathy, memory, comprehension, and judgment. They also produce fewer side effects such as seizures and tardive dyskinesia (involuntary body movements). In the following synthesis of clozapine, Step 1 is an Ullmann coupling, a type of nucleophilic aromatic substitution that uses a copper catalyst. (a) Show how you might bring about formation of the amide in Step 2. (b) Propose a reagent for Step 3. (c) Propose a mechanism for Step 4. (d) Is clozapine chiral? If so, how many of the possible stereoisomers are formed in this synthesis?arrow_forwardUsing your reaction roadmap as a guide, show how to convert cyclohexane into hexanedial. Show all reagents and all molecules synthesized along the way.arrow_forward
- Using your reaction roadmap as a guide, show how to convert 1-bromopropane and carbon dioxide into 4-propyl-4-heptanol. You must use 1-bromopropane and carbon dioxide as the source of all carbon atoms in the target molecule. Show all reagents and all molecules synthesized along the way.arrow_forwardUsing your reaction roadmap as a guide, show how to convert ethylene into 1-butene. All of the carbon atoms of the target molecule must be derived from ethylene. Show all intermediate molecules synthesized along the way.arrow_forwardIdentify the reagents you would use to convert 1-bromopentane into pentanamide. 1-bromopentane → pentanamide The transformation above can be performed with some reagent or combination of the reagents listed below. Give the necessary reagents in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer. A. excess NH3 D. H3O+, heat G. Na₂Cr₂O7, H₂SO4, H₂O B. NaCN E. SOCI2 H. 1) LIAIH4; 2) H3O+ C. Mg F. NaOH I. PCC or DMParrow_forward
- 3) A common practice that organic chemists work on is a process known as retrosynthesis. In this a chemist will take known reactants and devise a synthetic pathway to produce the desired products using reactions that they know. As you proceed through organic chemistry you will be tasked with thinking about this process. How would you make the desired final product starting from the alkyne. It will take a couple of reactions. Please show the reagents necessary. And for your last step please show the arrow pushing. Starting material Br Product Br ...arrow_forwardUsing your reaction roadmap as a guide, show how to convert butane into 2-butyne. Show all reagents and all molecules synthesized along the way. Butane 2-Butynearrow_forwardExplain this difference in potency and speed of onset by pointing out the main differences in functional groups between morphine and heroin.arrow_forward
- Describe a laboratory procedure that would allow you to form 2-pentanone and 3-pentanone from 2-pentyne. Show a synthesis pathway in your description, including the full structural diagrams for all reactants, products, and intermediatesarrow_forwardCompound A and compound B are in equilibrium. Write a stepwise mechanism from compound Ato compound B showing ALL intermediates. Use curved arrows to symbolize the flow of electrons to show how each of the intermediates and products are formed. Show all lone pairs and formal charges. Lastly, explain which compound (Aor B) will be in higher concentration.arrow_forwardChoose the best reagents from the list provided below for carrying out the following conversion.
