Arrange the following substances in order of increasing boiling point: CH₃OH, CH₄, CH₃CH₂OH, HOCH₂CH₂OH

Question

Quizplus · Accepted Answer

Boiling points increase with molecular weight and the ability to form hydrogen bonds. CH₄ (methane) has the lowest boiling point due to its small size and lack of hydrogen bonding. CH₃OH (methanol) has a higher boiling point due to hydrogen bonding. CH₃CH₂OH (ethanol) can form more extensive hydrogen bonding due to its larger size, increasing its boiling point further. HOCH₂CH₂OH (ethylene glycol) has the highest boiling point due to its ability to form multiple hydrogen bonds and its larger size.
