This strategy is called D2O exchange or, more colloquially, the “D2O shake.”. This exchange eliminates the OLH resonance (thus identifying it) and also eliminates any splitting between the a-protons and the OLH proton. The only splitting re- maining is then the splitting with any b-protons. high negative

The IR spectrum of aliphatic alcohols have a distinctive O-H stretch in the range of 3300 to 3400 cm -1. This peak tends to be very strong and very broad. This exact position of the peak is dependent on the amount of hydrogen bonding in the alcohol. In addition alcohol have a strong C-O stretch near 1000 cm -1. high neighbor
