Q: What peak pattern would you expect for the molecular ion of 1,1-dibromoethane?

A: Mass spectroscopy measures the mass to charge ratio of molecules present in a sample.

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.
