  1. Organic Chem - Identifying stuff the FAST way.
  2.  
  3. First off, smell it.
  4. Fishy/ammonia/eye watering smell - an amine, probably methylamine
  5. Paint thinner/Nail varnish remover - ketone
  6. Fruity/sweet - a nice ester?
  7.  
  8. If its a solid its probably an aldehyde.
  9. If solid, burn some. Smokey = aromatic, non smokey = aliphatic.
  10.  
  11. PROTIP IF LIQUID: Do the dinitrophenol test FIRST. Tells you if its aldehyde/ketone OR alcohol/ester OR some other shit.
  12.  
  13. Another tip - dont do 10 confirmatory tests. If its something its something. Just roll with it.
  14.  
  15. Srsly. Smell the stuff then give it some DNP then do a confirmatory, saves loads of time
