For each of the following organic compounds, list all of the IR absorption peaks that would be observed based on the bonds and functional groups that are present. Make sure to indicate whether each peak corresponds to a stretch or an out of plane bend. Note: For this question, there is no need to include the wavenumber range for each vibrational mode.

determination. Indicate what is causing the particular
absorption.
Annotate MS spectra
For NMR, label each signal ( a, b, c, ...) starting from the
right. Draw the structure of the compound and label the carbons and
protons using separate structures. Calculate the index of
unsaturation (U). Draw individual structures for each of the NMR
spectra (1HNMR and 13C) and annotate each.
