Question 6

An unknown oxygen-containing organic molecule shows a parent peak on its mass spectra at m/z 122. With no information from the visible or uv, the IR revealed major broad absorptions from 2500 cm¹ to 3500 cm¹, and strong sharp absorptions at 2930 cm^-1, 1690 cm¹, and 1230 cm¹. The ¹H NMR revealed a singlet downfield around d 13 (1H) and a multiplet at d 7.2 (5H). The molecule consistent with these facts is:
  A)
   
 
  D)
   
 
  B)
   
 
  E)
   
 
  C)
   
 

Question 7

An unknown hydrocarbon shows a parent peak on its mass spectra at m/z 86. There is no evidence of absorptions from visible or uv spectra. The IR shows no major absorptions outside the CH stretch and bending vibrations. The ¹H NMR reveals a singlet at d 0.9 (9H), a triplet at d 0.98 (3H), and a quartet at d 1.6 (2H).
