Which of the following alcohols has the highest boiling point?
A) 1-pentanol
B) 1,5-pentanediol
C) 1,3,5-pentanetriol
D) 1-butanol

Question

Quizplus · Accepted Answer

The boiling point of an alcohol depends on its ability to form hydrogen bonds. 1-pentanol, 1,5-pentanediol, and 1-butanol all have one hydroxyl group and can form intermolecular hydrogen bonds with each other. However, 1,3,5-pentanetriol has three hydroxyl groups that can each form hydrogen bonds, making it the most polar and capable of forming the strongest intermolecular forces. Therefore, it has the highest boiling point of the four options.
