Question

Why CO2 and NH3 can be liquefied easily where H2, O2 and N2 cannot be liquefied?

Answer 1

Answer:

So, since H2, O2 and N2 have very low or weak force of attraction among their molecules, therefore these gases cannot be liquefied. And as the molecular force of attraction is high in CO2 and NH3, so they can be liquefied easily.
