Given the molecules sulfur dioxide (SO2) and sulfur trioxide (SO3), sulfur dioxide (SO2)sulfur dioxide ( S O Subscript2 ) Given the molecules sulfur dioxide ( S O 2 ) and sulfur trioxide ( S O 3 ) , blank has the higher boiling point mainly due to blank. has the higher boiling point mainly due to molecule shape and stronger dipole-dipole interactionsGiven the molecules sulfur dioxide ( S O 2 ) and sulfur trioxide ( S O 3 ) , blank has the higher boiling point mainly due to blank..

Answer 1

Answer:

Phosgene has a higher boiling point.

Sulfur trioxide has a higher boiling point.

Explanation:

Phosgene has a higher boiling point than formaldehyde because it has a larger molar mass.

Sulfur trioxide has a higher boiling point due to its molecular shape (trigonal planar) and stronger dipole-dipole interactions. Furthermore, it has a larger molar mass.
