Which of the following statements is true regarding the proton signals for H₂ and H₂ in the ¹H NMR spectrum of compound A? Ha A Ha and Hb would not couple to each other, as they are chemically equivalent via the symmetry of compound A The coupling constant for the Ha to Hb coupling (Jab) would be larger than for a typical linear chain, due their relative orientation in the most stable conformation of A Ha and Hb would both appear in the spectrum with a complex doublet of triplet of quartets splitting pattern The chemical shifts for H₂ and Hb would be greater than 2 ppm apart, due to their different relative distances from the t-butyl group H₂

Answer the following questions on using IR spectroscopy to characterize the products in the synthesis ofluminol.a. Can IR be used to determine if the synthesis of the hydrazide was successful? Explain youranswer.b. IR cannot be used to determine the success of the reduction of the nitro group into an amine in Part II.Explain why not.
The NMR spectrum of 3-nitroaniline was taken in deuterated dimethylsulfoxide (DMSO), not CDCl3. Why? a) The residual CHCl3 peak would get in the way of the aromatic peaks in the product.b) 3-Nitroaniline is not soluble in CDCl3.c) DMSO allows visualization of the peaks for the NH2 group.d) 3-Nitrobenzamide is not soluble in CDCl3.

Please provide a structure consistent with the following IR, 13C NMR, and 1H NMR spectra. Assign at least two bands in the IR and assign all protons in the 1H NMR/13C NMR spectrum. Show calculation of degree of unsaturation and explain your reasoning.
Many studies have shown that one specific enantiomer of citalopram (“S”) is the one capable of inhibition of serotonin reuptake. Lexapro is the brand name for the purified form of the S- enantiomer of citalopram. Explain briefly why Lexapro would be more expensive than Celexa.
Deduce the strcuture of compound E2 for which spectral data is provided. Make assignment for all of the spectral peaks which you can by writing directly on the spectral traces. Make these assignments in terms of structures of fragments or functionalities whenever possible. Draw the proposed structure.

Suggest structures given the 1H NMR spectra and formulas for each of the compounds below. C10H14, two peak area ratio is 1:6
If the imaginary replacement of either of two protons forms enantiomers, then those protons are said to be enantiotopic. The NMR is not a chiral probe, and it cannot distinguish between enantiotopic protons. They are seen to be “equivalent by NMR.” What other protons in cyclobutanol are enantiotopic?
Suggest structures for the following compounds that are consistent with the following formulas and 1H NMR data (multiplicity and relative peak integration). Where appropriate, IR data is given.
