Gases posses characteristic critical temperature which depends upon the magnitude of intermolecular forces between the particles. Following are the critical temperatures of some gases.
`{:("Gases",H_(2),He,O_(2),N_(2)),("Critical temperature in kelvin",33.2,5.3,154.3,126):}`
From the above data what would be the order of liquefaction of these gases ? Start writing the order from the gas liquefying first

Options

A. `H_(2) , He , O_(2) , N_(2)`
B. `He , O_(2) , H_(2) , N_(2)`
C. `N_(2) , O_(2) , He , H_(2)`
D. `O_(2) , N_(2) , H_(2) , He`

Answer

D

Explanation

Gas with highest critical temperature can be liquified easily .
