WebFigure 6.4a IR Spectrum of 1-hexanol. In the IR spectrum of 1-hexanol, there are sp3 C-H stretching bands of alkane at about 2800–3000 cm-1 as expected. Other than that, there is a very broad peak centered at about 3400 cm-1 which is the characteristic band of the O-H stretching mode of alcohols. Figure 6.4b IR Spectrum of 1-octene.
