Critical temperature is the temperature above which gas cannot be liquefied, regardless of the pressure applied.
Critical temperature directly depends on the force of attraction between atoms, it means stronger the force of higher will be the critical temperature. So, from the given options H2 should have the highest critical temperature because of high attractive forces due to H bonding.
Hence, the correct option is H2.
Explanation:
impurities affect both melting point and boiling point
in the case of melting point it lowers the melting point
so I guess one of the samples Ie contained impurities
