Question

The following three compounds have similar molecular weights. Place them in order of increasing boiling point. Formaldehyde: H₂C=O methanol: CH₃OH ethane: CH₃CH₃

Quizplus · Accepted Answer

Ethane has the lowest boiling point due to its nonpolar nature and lack of hydrogen bonding. Formaldehyde has a higher boiling point due to its polar nature but lacks hydrogen bonding. Methanol has the highest boiling point because it can form hydrogen bonds.
