Give one fragment in the mass spectrum and one peak in the IR spectrum that could be used to distinguish between these two isomers: Give one fragment in the mass spectrum and one peak in the IR spectrum that could be used to distinguish between these two isomers: CH O CH (O H3C H3C H3C CH 3,3-dimethylbutanal 4-methylpentan-2-one (Designate which compound will show that diagnostic fragment or peak by preceding the value with the letter of the compound, i.e. "a47"...
The low-resolution mass spectrum of an unknown monosubstituted benzene showed a molecular ion (M+) peak at m/z 150. Combustion analysis of a sample of this compound indicated that the compound contained C, H, and O only and had an empirical formula of C3H1002. The IR spectrum of the unknown compound is shown below. The 'H NMR spectrum of the unknown compound did not show a peak in the 9.10 ppm range. D 4000 9000 2000 1500 1000 RAVENUGERII What is...
1450–1600 Medium At what approximate positions might this compound show IR absorptions? Consult the table given above; there must be an exact match of groups with the absorptions. There are occasional overlaps between absorptions in the table, be sure that the group is actually present in the molecule. Esters and alcohols both show similar C-O stretching vibrations. Enter your choices as an alphabetized string of letters, with no spaces. Table of IR Absorptions a. 2850-2960 b. 3020-3100 1640-1680 d. 3300...
