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

should assign peaks that were important in making your structural
interpretation (i.e. functional group peaks such as OH, C=O, N-H,
etc.).
