Distinguishing between Organic Molecules
Not what you're looking for?
Question: What chemical tests might be used to distinguish between: pentanal and 2-pentanone, between benzyl alcohol and diphenylmethanol? I believe that the tests to distinguish pentanal and 2-pentanone can be: NMR spectrometry and a 2,4 dinitrophenylhydrazine test. The tests to distinguish benzyl alcohol and diphenylmethanol can be NMR spectrometry again and a melting point test.

Your question says how to distinguish between these species .It does not say chemically or spectroscopically. Chemically you can distinguish any aldehyde from a ketone by a silver mirror test (Tollen's test) and a diphenylhydrizine test. However, a very authentic test to distinguish aliphatic from aromatic is by putting a ...
