Argon, oxygen, and nitrogen are obtained from air by fractional distillation. Liquid air, at 250°C, is warmed up, and the gases are collected one by one.
Explain why fractional distillation is used, rather than simple distillation.

during fractional distillation every steps gives a product and its much more complex than simple distillation

Their boiling points are
Oxygen. -183 Celsius
Argon -186 Celsius
Nitrogen. -196 Celsius
As their boiling points are very near,simple distillation will not be effective( They may get mixed again in the collection tank).
So fractional distillation method is used.
