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.

- 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_forwardFor each reaction in question 20, sketch a reaction coordinate energy diagram indicating the starting materials, transition states and any intermediates, if present, in the reaction. Don't worry about the absolute energy of starting materials and products but you can assume that the product is more stable than the starting materials.arrow_forward
- 4. A CHEM 245 student wants to synthesize some ethylene glycol to use as antifreeze in his radiator this winter. He proposes the following reaction to his instructor, who quickly explains that this reaction won't work as proposed due to the student's choice of reagent. 1) NaH 2) H20 OH Но a) Why can't sodium hydride (NaH) be used as the nucleophile in the reaction above? b) Propose an alternate reagent that COULD be used with the ethylene oxide to successfully give the desired ethylene glycol product.arrow_forwardN,N-diethyl-m-toluamide (DEET) is the active ingredient in many insect repellent preparations.

The biosynthetic pathway involves the cyclization of this acetal from the straight chain structure. Draw the straight chain structure that could be used to form this acetal. Use wedges and dashes to correctly depict the stereochemistry.
