Which of the following alcohols has the lowest boiling point?
A)1-pentanol
B)1-octanol
C)1-hexanol
D)1-propanol

Question

Quizplus · Accepted Answer

The boiling point of an alcohol primarily depends on the size of its molecule and the strength of its intermolecular forces. 1-propanol has the lowest molecular weight and therefore the weakest intermolecular forces among the four given alcohols, leading to the lowest boiling point. The boiling points increase with an increase in carbon chain length (A, C, B) due to the stronger intermolecular forces.
