Concept

Problem: The IR spectrum of benzoic acid is included on page 3. Assign three specific absorbance bands (from the peak list below the spectrum) to the corresponding bond vibrations. Select three distinct bond vibrations, in other words, do not list three absorbance bands that are all due to arene C-H stretching. Your answers should be submitted in the following format (a different compound, acetophenone, is used as an example)IR Spectrum of Acetophenone1. 1691 cm-1, ketone C=O stretch
