Provide the correct structure for your unknown based on the
spectroscopic data provided. Provide the correct name for your
compound. Either the IUPAC name, or a commonly accepted name (i.e.,
ethyl acetate in place of ethyl ethanoate) will be accepted.IR
spectrum: Assign as many peaks as possible. In particular, you
should assign peaks that were important in making your structural
interpretation (i.e. functional group peaks such as OH, C=O, N-H,
etc.).

Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...
