Q-5 Interpret the following EI mass spectra; give one possible structure of the compound. 100 139 Mass=156 80 60 111 40 75 50 158 20 38 0.0 40 80 120 160 200
Elemental analysis determined unknown Compound G to contain 40.0 % carbon, 6.7 % hydrogen. Compound G had an M+ = 60 m/z on its MS. Its IR displayed three absorbances: strong at 1710, strong below 3000, and broad from 2500 to 3500. The proton NMR showed an absorbance at 1.7 ppm (lowest whole number ratio of H =3), and an absorbance at 11.5 ppm (lowest whole number ratio of H = 1). Compound G was able to turn blue litmus paper red, and neutralize a base. What is Compound G? O CH3CO2H O Formaldehyde O HO C CH2 HO O CHy(OH)CHO O CHOHHCH(OH)
Choose the best explanation for why -OH and -NH peaks are often broad singlets in a ¹H NMR spectrum. A) The greater electronegativity difference in the N-H or O-H bond compared to a C-H bond makes the peak broader. B) The greater mass involved in the N-H or O-H bond compared to a C-H bond makes the peak broader. C) The hydrogen nuclei on the carbon next to the -OH or -NH are too far away to impact the multiplicity. D) Protons in OH or NH groups are acidic enough to rapidly exchange between different molecules, so the coupling to vicinal hydrogens is not clearly observed.
Which one is the incorrect statement regarding mass spectrum? The structure likely contains a bromine atom if the (M+2)+ peak and (M)** are almost similar in heights The relative heights of (M)** peak and (M+1)** peak indicate the number of carbon atoms A signal at M-15 indicates the loss of a methyl group and a signal at M-29 indicates the loss of an ethyl group In case of alcohols, a signal at m/z = 18 is produced due to the loss of neutral H₂O molecule (Dehydration) The structure likely contains a chlorine atom if the (M+2)** peak is approximately one-third as tall as (M)*•
After submitting a sample for mass spectral analysis you are given the following spectrum: 100 80 - 60 40 20 – 10 20 30 40 50 60 70 80 m/z You know that your sample is either 3-pentanone or 3-pentanol. OH 3-pentanone 3-pentanol Part A: How could you use the mass spectrum above as your only means to determine if your sample is either 3-pentanone or 3- pentanol? Note that the spectrum above lacks a molecular ion. Part B: What is the identity of the sample which provided you with spectrum above: 3-pentanone or 3-pentanol? Relative Intensity
