    Characteristic IR Absorption Frequencies
    You will need to consult the characteristic frequencies table.

    4. The IR spectrum of a carboxylic acid is shown below. What are the approximate wavenumbers of the stretching absorptions due to the C=O and O-H bonds?
     
    IR spectrum of a carbocylic acid  
    (a) C=O: cm-1

    (b) O-H: cm-1


    (This question is for self assessment and your answer and score will not be recorded.)
