Question

1. You are given an impure sample of a phenol and asked to purify it. You ask for information about the suspected impurities, but it seems no one really knows. So you ask for an IR/NMR spectra of the impure sample. Upon scrutinizing the IR spectrum carefully, you find that there is a small, but significant, signal at about 1700 cm-1, a small broad peak at about 3000 cm-1 and a much stronger broad peak centered at about 3580 cm-1. That gives you an idea about the nature of the impurity, so you scrutinize the 13C NMR spectrum, looking for a short signal at ~170 ppm- you find it. You then look for a signal in the 10-13 ppm range in the 1H NMR spectrum- there seems to be a little

Explanation / Answer

What are you guys all retarded? It says 3000 not 3300...quit copying and pasting answers...this isn't even the same question!
