1. shown below are IR spectra of cyclohexanecarbaldehyde (I)
and cyclohexene (II). which of the spectra A and B corresponds to
which structure (I or II)? On each spectrum identify the peaks that
are associated with a specific bond vibration bond by drawing the
functional group for that bond, circling the specific vibrating
bond and drying and arrow from the circled bond to the absorption
peak. include all the C-H bonds.
