Distinguishing between Organic Molecules
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.
