The CH3 bend appears at 1450 and 1375 cm-1, whereas the CH2 bend appears at 1465 cm-1.
All these three bending absorptions are present in the given IR spectrum.
Hence, most probably, the given IR spectrum corresponds to trans-2-pentene (First row, third one).

instructions.
Attached are 2 sets of spectra. Each set is worth 25 points. Not all sets have a Mass Spectrum, but do have information that was obtained from MS and some sets do not have a "C-NMR and don't really need one. Look at each spectrum individually and clearly list and comment on the structural Characteristics you can determine from that spectrum.
