What one test(not using the semicarbazone or 2,4-DNP derivatives) could be used to differentiate between the following pairs? Describe what you would observe. a. 2-Pentanone and 3-pentaone
b. Pentanal and 3-pentanone
c. 1-Propanol and 2-propanol
3. Indicate which of the following will give a positive iodoform test:.
acetone 2-pentanone 3-pentanone cyclohexanone
2-methylcyclohexanone ethanol 1-propoanol 2-propanol
t-butyl alcohol acetaldehyde propionaldehyde
4. An unknown compound's semicarbazone melts at 162-165 degree C. The compound does not give a silver mirror in the Tollens' test. On reaction with KI/I_2, NaOH/H_2O no straw yellow precipitate forms. Identify the unknown. Explain your reasoning.
