Question
1. What is the purpose of making derivatives of unknowns? 2. Why are 2,4-dinitrophenylhydrazones better derivatives than 3. Using chemical tests, how would you distinguish among 2-pentanone, 4. Draw the structure of a compound with the empirical formula C,H,O that 5. Draw the structure of a compound with the empirical formula C,HgO that phenylhydrazones? 3-pentanone, and pentanal? gives a positive iodoform test and does not decolorize permanganate. gives a positive Tollens' test and does not react with bromine in dichloromethane.Explanation / Answer
Answer 1
The formation of derivative from unknown compound is used for identification purposes.Chemical derivatives can be used to facilitate analysis. For example, boiling point (BP) or melting point (MP) analysis can assist in identification of many organic compounds.
