Ammonia is more easy to liquefy than oxygen, then which of the following is true about oxygen as the reason for this fact?

Question

Ammonia is more easy to liquefy than oxygen, then which of the following is true about oxygen as the reason for this fact? (A) It has high critical temperature. (B) It has low critical temperature. (C) It has high bond dissociation enthalpy. (D) Its electronegativity is high.

Tardigrade Admin · Accepted Answer

Critical temperature of a gas is highest temperature at which liquifaction of the gas first occurs. The gases having higher critical temperature are easier to liquefy. Thus, as per the information given in question, the correct reason would be that oxygen has lower critical temperature than ammina.
