Quiz #6 Distillations, Boiling Point and Gas Chromatography 1. The boiling point is measured: a. above the surface of the liquid b. in the boiling liquid itself c. in the receiving flask d. with a thermometer external to the distillation apparatus 2. In a distillation of a mixture of two components, the first compound to condense into the receiving flask will be the one with the lower melting point the one with the higher melting point the one with the lower boiling point the one with the higher boiling point a. b. c. d. 3. The greater the surface area of the packing of the fractionating column, the greater its efficiency the lower its efficiency efficiency does not depend on the surface area of the column the faster the distillation will proceed a. b. c. d. 4. In gas chromatography, the sample is injected with a syringe into the gars a. directly onto the column b. through the heated injection port c. into the detector d. into the recorder 5 .The greater the surface area of the packing of the fractionating column a. the greater its efficie b- the lower its efficiency c. efficiency does not depend on the surface area of the column d. the faster the distillation will proceed ncy aporized GC sample is carried through the heated column by a. a stream of air b. an inert carrier gas (helium or nitrogen) 6·The v c. the adsorbent d. steamm
