#4. the 1H NMR spectrum of an alcohol (and amine) often depends on severial variables such as concentration and temperature. Sketch the expected 1H NMR spectrum of the following alcohol under each condition. Under conditions in (a) hydrogens on carbin do NOT split (couple) with hydrogens on oxygen. Under conditions in (b) hydrogens on carbon split (couple) with hydrogens on oxygen. For (c) explain the change in the spectrum.
