Question

Place the following substances in order of increasing vapour pressure at a given temperature. NF₃ NH₃BCl₃ A) NH₃ < NF₃ < BCl₃ B) NF₃ < NH₃ < BCl₃ C) BCl₃ < NF₃ < NH₃ D) NH₃ < BCl₃< NF₃ E) BCl₃ < NH₃ < NF₃

Quizplus · Accepted Answer

Ammonia (NH₃) has strong hydrogen bonding, resulting in the lowest vapor pressure. NF₃ has weaker intermolecular forces than NH₃ but stronger than BCl₃, which has the weakest forces and thus the highest vapor pressure.
