Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

The labels on two bottles were not properly secured and they came off. One bottle contains cyclohexanone and the other contains cyclohexanol. List three ways (besides the example below) that could tell you which liquid is in which bottle, and describe how your results would distinguish between two liquids. Not all these ways need to employ spectroscopy. Do not simply name tests or techniques. Instead, describe what you would observe. For example, "Cyclohexanone would give a positive DNP test and a negative chromic acid test, but cyclohexanol would give a negative DNP test and a positive chromic acid test." (You may wish to look up the properties and structures of these compounds in a catalog or handbook before answering.)
