Which of the following compounds will have the lowest boiling point?
A) butanoic acid
B) 1-proponol
C) acetic acid
D) propanal

Question

Quizplus · Accepted Answer

Propanal will have the lowest boiling point because it lacks the ability to form hydrogen bonds as effectively as the other options. Butanoic acid, 1-propanol, and acetic acid can all form hydrogen bonds due to their -OH groups or the acidic hydrogen in the case of the acids, leading to higher boiling points. Propanal, being an aldehyde, does not have this capability and thus has a lower boiling point.
