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.
