On spectra 1 are the mass, IR and 13 C and 1 H NMRspectra of an organic compound.1) a) From these spectra, determine the structure of the molecule.Remember to ignore the triad in the 13 C NMR spectrum at 77 ppm thatcomes from the NMR solvent. b) Draw the structure of the molecule and label each hydrogen with a letter(A, B, C...). Then fill in the peak assignment table below.  hydrogen chemical shift integration splitting pattern couples to

For 4-acetylbenzonitrile, can you please annotate 1. Each of the hydrogen labels (please show on structure!) 2. The predicted chemical shift 3. The splitting pattern 4. The integral value for each hydrogen? Please help!!! 5. Other solvents / impurities? * Small peak at 7.2-3 ppm is CDCl3 (It is a solvent I used in lab for NMR prep) Please help!!! I want to know if I'm on the right page.

From the given IR and mass spectra of the unknown compound:   1. Which element is surely present in the compound? a. F b. O c. Br d. N 2. Which statement is true? a. It has no saturation b. It is an acid anhydride c. It contains -CH2- next to benzene ring d. All are false

Analyze the spectra and write the name of compound. Also write brief explanation for each spectra verifying the parts of your suggested molecule ( for IR indicate the functional groups which match is the peaks. for mass indicate the fragments. for CNMR an HNMR indicate which peak belongs to what).

Please help with determining the functional groups present in the IR data results of our isoamyl acetate sample. And the "bond and bond motion" that causes those peaks . I believe the sharp peak at 1700 is a C=O bond.  Thank you in advance!

Why is it important for solutions to be diluted before they are run through spectroscopy?

urgent plsd help : how do you know the chemical shift of the nmr of a chemical for example nylon 6,10 . how do you knoe if  it shift to the left (downfield) suggesting deshielding (more electronegative environment) or a Shift to the right side suggesting shielding (less electronegative environment)

Information: Each spectra below was obtained from a pure compound. Mass Spectrum parent peaks (M) are listed for all examples. IR peaks listed are strong (s) unless otherwise indicated for signals above 1500 cm¹ 'H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given showing a "zoom-in" on an important part of the spectrum.
