Interpretation: To assign the various resonances to the hydrogen nuclei of 2-bromo-2-methylbutane in
Concept Introduction: Nuclear magnetic resonance (NMR) is a spectroscopy technique that works on the basis that the nucleus of the atoms absorbs
(b)
Interpretation: To assign the various resonances to the carbon nuclei of 2-bromo-2-methylbutane in
Concept Introduction: Carbon-13 NMR has several merits over proton NMR in terms of its power to explain biochemical and organic structures. Carbon-13 NMR provides information related to the backbone of molecules instead of the periphery. In addition, the chemical shift range for Carbon-13 for most organic compounds is around 200 ppm related with 10 to 15 ppm for the proton.

- Aromatic electrophilic substitution-Nitration of Bromobenzene experimentarrow_forwardWrite a mechanism that accounts for the formation of ethyl isopropyl ether as one of the products in the following reaction. A. Write the mechanism for step one of this reaction. Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. B. Write the mechanism for step two of this reaction (where the product of step one reacts with the solvent, ethanol). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. C.Write the mechanism for the last step of this reaction (formation of ethyl isopropyl ether). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. Cl- will act as the base in this reaction.arrow_forward1. Summarize the main characteristics of nucleophilic acyl substitution. 2. Choose one carboxylic acid that has applications in diagnostic tests, nutrition, or pharmacology. Explain how the molecular property contributes to the bulk property of the carboxylic acid.arrow_forward
- Mechanism. Consider the following reaction... HNO, (1 eq.) HSO, 0°C "NO: NO2 MA JOR MINOR a. Draw the mechanism for the formation of the EAS electrophile for this reaction. What is the role of sulfuric acid in this process? b. Draw all of the possible resonance forms for this reaction's sigma complex, as well as the resonance hybrid structure. c. Using both pictures and words, explain the regioselectivity of this reaction, or why the nitro group was added to the designated carbon.arrow_forwardNitration of furan with acetylnitrate leads to 2,5-dinitrofuran. Mononitration can be done by A. carrying out the reaction at higher temperature. B. using nitric acid instead of acetyl nitrate. C. carrying out the nitration in the presence of pyridine D. using concentrated nitric acid/sulfuric acid instead of acetyl nitrate.arrow_forwardPropose a structure for an aromatic hydrocarbon, C3H10, that can form three C3H,Br products on substitution of a hydrogen on the aromatic ring with bromine. • You do not have to consider stereochemistry. In cases where there is more than one answer, just give one. • Ignore the ortho, para-directing effects of the alkyl groups in answering this question. Consider only the number of nonequivalent hydrogens on the aromatic ring. .... ChemDoodlearrow_forward
- Exp3: Diels-Alder reaction Why does cyclopentadiene regularly form a dimer? How to break the dimer into monomers? Does the diene in this reaction act as the nucleophile or the electrophile? Is the maleic anhydride a nucleophile or an electrophile in this reaction? Explain your reasoning.arrow_forwardD. Halogen-sp³ carbon bonds are often used as electron pair acceptors, known as electrophiles, in organic reactions. Electrophiles typically use their LUMO to an accept an electron pair from a donor known as a nucleophile. Given your knowledge of M.O. theory please predict what would happen if the nucleophile HS-would donate a lone pair of electrons to the LUMO of chloromethane. Please explain your prediction.arrow_forwardWhich of the statement is INCORRECT? a. The increase in stability of 2,4-hexadiene over 1,3-hexadiene is due to the increased double bond substitution of the former. b. The stabilization of dienes by conjugation is less pronounced than the aromatic stabilization of benzene. c. Resonance description in alkenes usually involves charge separation. d. Higher energy pi-orbitals often have decreasing number of nodes.arrow_forward
