Determine the identity of the Unknown B compound given the IR spectrum, H NMR spectrum, and observed experimental melting point. Label the absorptions for the IR spectrum and label & match the protons of the structure you identify to the signals on the H NMR spectrum. The observed melting point in the experiment: ~47.5-54 degrees celsius. Attached is a list of possible compounds based on m.p. from appendix to help narrow the possibilities. If you could please help me with this problem as I am having a lot of trouble with this question, I would really appreciate it.

Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.
