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.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
