- 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.An oxidation reaction was conducted using cyclohexanol and NaOCl to make cyclohexanone. How can we know that the IR spectra for cyclohexanone is in fact cyclohexanone apart from the title. Analyze and annotate the IR spectra to prove its identity.Determine which of the following belongs to this ir spectra then complete the nmr analysismethyl butanoate benzaldehyde 1-chlorobutane 1-chloro-2-methylpropane butan-2-one propan-2-ol propanal
- How does the proton (1H) NMR of the methyl benzoate reagent compare to the methyl 3-nitrobenzoate product? Include (or illustrate) the NMR plots and peak assignments for each please type out so i can read clearlyTreatment of compound C (molecular formula C9H12O) with PCC affordsD (molecular formula C9H10O). Use the 1H NMR and IR spectra of D todetermine the structures of both C and D.When 1-bromobutane is treated with sodium acetate (CH3CO,Na), the major product for the reaction is an ester (CH;CO2CH2CH2CH2CH3). Explain how mass spectrometry and IR spectroscopy could be used to prove that the reaction has occurred and you no longer have the starting material.

Describe for differences in structure that account for the most significant differences between these two spectra and which peaks shifted most significantly.AThe oxidation of 3-pentanol to 3-pentanone was performed in the lab and an IR was taken of the finished product. (a) what are the key functional groups in the starting material, 3-pentaol? (b) what are the key functional groups in the product, 3-pentanone? (c) based on the IR spectrum below, was the experiment successful, and, if so, how pure was the product? Explain your reasoning.
