Which gas is fractional distillation of liquid air???? If any one know plzz guide me!!!

Nitrogen first separate because of its lowest boiling point- 196°C then Argon and lastly oxygen.

But in past papers carbon dioxide is fractional distillation of liquid air....

So confusing McQ ....
Dr.slump🩺🫀 · 2026-07-22T18:35:49.272Z
What is the correct statement.
nooraly · 2026-07-22T18:42:27.471Z
I guess the correct is carbon dioxide.... I'm right??? Because options are carbon dioxide, oxygen, hydrogen, methane .... What u think???

If asking about CO2 it must be removed first beacuse of impurities otherwise,it will freeze

Why it's freez???

Option mein Oxgen dia hai to oxygen choose krenge.fractional distillation mein gases ko based on boiling point remove kia jaata hai.to pehle number pr nitrogen hoga or dosre number pr Argon third pe oxygen.Co2 ko pehle hi remove krdia jaata hai

So oxygen is right option..
Dr.slump🩺🫀 · 2026-07-22T18:53:56.794Z
Or C02 isliye freeze hojata hai qk isme sublimation hoti hai gas se direct dry ice mein convert hojata hai isi liye pehle hi remove krdia jaata hai.

Dr.slump🩺🫀 · 2026-07-22T14:14:18.545Z
Nitrogen,Oxygen,and argon
nooraly · 2026-07-22T16:15:54.018Z
Oxygen hoga ???
