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.).

I kind of know where to start for these but I get so confused
trying to draw the structure and how to read and interpret the
CNMR. Looking at the IR frequencies i think there is a benzene
ring, as well as sp2 and sp3 C-H bonds, there is no O-H or N-H
bonds, as well as no carbon triple bonds to nitrogen or carbon, and
no carbon double bonded to oxygen bonds.I know there has to be 8
