Question

It is possible to obtain oxygen from air by fractional distillation because (A) oxygen is in a different group of the periodic table from nitrogen (B) oxygen is more reactive than nitrogen (C) oxygen has higher boiling point than nitrogen (D) oxygen has a lower density than nitrogen

Tardigrade Admin · Accepted Answer

Oxygen gas is prepared by fractional distillation of air. During this process, dinitrogen with less boiling point (78 K) distills as vapours while dioxygen with higher boiling point (90 K) remains in the liquid state and can be separated.
