It is eaiser to liquefy oxygen than hydrogen because.

Options

A. oxygen has a higher `T_(c )` and lower inversion temperature `(T_(i))`
B. oxygen has lower `T_(c )` and higher `T_(i)` than hydrogen
C. oxygen has a high `T_(c )` and high `T_(i)` than hydrogen
D. oxygen has lower `T_(c )` and low `T_(i)` than hydrogen

Answer

C

Explanation

`(c )` is the correct answer because `O_(2)` has higher molecular weight than `H_(2)`, more surface area, move van der Waals forces of attraction, hence has higher `T_(C )` and higher `T_(i)` (inversion temperature).
