Fractional distillation refers to taking different volatile substances off at different temperatures. To fractionally distill air the differences in boiling points of its two main components oxygen and nitrogen are used.
Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide.
Nitrogen boils at −196 °C
Oxygen boils at −183 °C
Argon boils at -186.0 °C
Carbon dioxide sublimes at -78.5 ºC
If the air mixture is cooled to -200 ºC then theoretically all the gases are liquids. As the temperature is carefully increased then nitrogen would boil off at -196 ºC leaving the other gases as still liquid. The nitrogen thus is collected. As the temperature is slowly increased past -183 ºC the oxygen could be collected etc.
Alternatively, the temperature could be slowly decreased and the solid carbon dioxide collected when the temperature drops below -78.5 ºC. Next liquid oxygen is collected at just below -183 ºC leaving the other components of air still as gases, and so on...

What gas is obtained by fractional distillation?
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
Which liquid would be the first to be collected in the fractional distillation?
The liquid with the lowest boiling point will be the first to be collected in fractional distillation. This is because it vaporizes at a lower temperature and rises first in the fractionating column before condensing.
How do humans get the element xenon?
Xenon is obtained as a byproduct of separating and purifying air, where it is present in trace amounts. It can also be extracted from certain minerals or as a byproduct of nuclear fission reactions. Commercially, xenon is typically obtained through fractional distillation of liquid air.
Which one of the following is not obtained by the fractional distillation of water he or xe or ne?
Xe (xenon) is not obtained through the fractional distillation of water. Xenon is a noble gas and is typically obtained through the fractional distillation of liquid air. Water can be fractionally distilled to obtain gases like hydrogen and oxygen, and neon can also be obtained through fractional distillation processes.
How is xenon obtained?
Xenon is obtained through the fractional distillation of liquid air. It is present in the Earth's atmosphere in trace amounts and can be extracted by separating it from other gases using processes such as cryogenic distillation or adsorption. Xenon is a byproduct of some industrial processes, such as the production of oxygen and nitrogen.
