The mass spectrum of compound A shows molecular ion peak at m/z 88. The IR spectrum of this compound has a broad peak between 3200 and 3550 cm-1. The 1H NMR spectrum of A shows the following peaks: a triplet at d 0.9, a singlet at d 1.1, one more singlet at d 1.15, and a quartet at d 1.6. The area ratio of these peaks is 3:6:1:2. The 13C NMR contains 4 signals. In the space below, propose a...

Please help identify the
organic compound using mass spec, ir spec, CNMR, and HNMR.
From looking at the mass spec, I believe the molar mass of the
uknown organic compound to be 122 g/mol
From looking at CNMR, I believe there are at least 5 carbons for
each of the 5 peaks. I recall from class that there can be more due
to symmetry, but am not certain how to tell.
Above are all of the graphs given to me...
Need help proposing a structure given the following
data.
23. The mass spectrum shows M = 72, IR shows a strong peak near 1720 cm! C-NMR shows four lines. The proton NMR is tabulated below. 2.4 ppm (2H quartet) 2.1 ppm (3H singlet) 1.1 ppm (3H triplet)
please go into some depth about how you used the mass
spec to elucidate the structure (I'm really bad at Mass spec).
thanks!!
