Which of the following compounds has the lowest boiling point?
A) acetone
B) formaldehyde
C) 3-octanone
D) cyclopentanone

Question

Quizplus · Accepted Answer

Formaldehyde has the lowest boiling point because it is the smallest molecule and therefore has the weakest intermolecular forces between molecules. Acetone, 3-octanone, and cyclopentanone all have larger and more complex structures, leading to stronger intermolecular forces and higher boiling points.
