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

    3. The IR spectrum of 2,6-dibromoaniline is shown below. What are the approximate wavenumbers of the stretching absorptions due to the N-H and C=C bonds?
    (Hint: there are 2 N-H stretching vibrations.)
     
    IR spectrum of 2,6-dibromoaniline  
    (a) N-H: cm-1 and
    cm-1


    (b) C=C: cm-1


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