which peaks can be expected when 5-methylhexane-2,4-dione is analyzed by mass spectrometry?

The 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.

How can you distinguish aldehydes, esters and carboxylic acids using IR spectra? Explain using specific examples.

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.

Annotate the Mass Spec, 1H NMR, and 13C NMR for C4H11N or Butylamine Annotate the Mass Spec, 1H NMR, and 13C NMR for C4H8O or Butraldehyde Annotate the Mass Spec, 1H NMR, and 13C NMR for C5H8O or Cyclopentanone Thanks :)

Show how the compounds with the molecular formulas C6H9N and C5H5NO can be distinguished by the m/z ratio of their molecular ions in high-resolution mass spectrometry.

Which one of the following statements is not true? O In mass spectrometry, the initially formed radical cation can sometimes survive and appear as a peak on the mass spe O Visible light is higher in energy than infrared light. O In mass spectrometry the peak corresponding to an ethyl cation fragment would appear at m/z 30. O In mass spectrometry, a benzylic cation would appear at m/z 91. O In IR spectroscopy, a C-O bond stretch would appear at a lower cm1 than a C=O bond stretch. %23 $ & 8 2 3 4 6 8 Q E R T. Y 4 5 2 K D G H. C || N M. alt

Which pair of compounds would be most easily distinguished by mass spectrometry? A) 1,2-dimethylbenzene and 1,4- dimethylbenzene B) 2-chloropentane and 3-chloropentane. C) 2-chlorobutane and 2-bromobutane. D) Octane and 2,2,4-trimethylpentane. E) NO and CH20.

Please help me identify the H1 NMR peaks for the compound as seen in the photo!

Look at the structure of ethyl acetate in your notebook. In which region of the 13C spectrum of ethyl acetate would you NOT expect any peaks?     a.0 - 50 ppm b.50 - 100 ppm c.100 - 160 ppm d.160 - 220 ppm
