Provide a brief explanation as how you could use the various forms of spectroscopy to give you an indication that you have 100% conversion of alcohol to alkene? Use specific signals to support your answer.
IR spectroscopy would not be useful in this way. Why not? Although IR gives definite absorption bands for alcohols verses alkenes, it won't be sensitive enough to determine whether or not you have a pure sample.
However, mass spectroscopy is good for this. How come? The mass of an alcohol is 18 amu greater than the corresponding ...
