Which of the following 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 among the given options and has the weakest intermolecular forces. Acetone and 3-octanone have higher boiling points due to the presence of a larger and more polarizable carbonyl group, while cyclopentanone has a higher boiling point due to its cyclic structure which leads to closer molecular packing and stronger intermolecular forces.
