Fill in the following by identifying the peaks you labeled in your spectrum. Assign the peaks to the functional group vibrations listed. More than one peak (label) may appear for a vibration of a functional group .Functional Group Vibration Aromatic C-H stretching vibration Ketone C O stretching vibration cop bending vibration on monosubstituted aromatic ring (phenyl)..

Determine splitting for all CHx groups using n+1 rule then match to appropriate spectrum drawing CH or OH group above each of the peaks.
