Document Summary

This c-h stretching is characteristic of a aromatic ring, it doesn"t have very sharp peaks just below 3000, it has tiny peaks. The peak corresponding to the alcohol near 3200 is rather smooth, tall, strong peak. This is very different than the ch peak in this region. overtone feature of lower than. An aromatic ring usually has two strong peaks in the area of 700. The two small peaks are characteristic of amines, near the 3300. These can be larger and extend up to mid way. Here we have two, if we have one bend it means we have one nh bond, and if we have two peaks then we have. For an aldehyde the hydrogen in the -cho results in a different pattern of the. There is a small distinct peak, highlighted in red, that is not usually seen but is present in this case.
