Rank the following molecules in order of increasing normal boiling point: CH₃CH₂OH,CH₃CH₂CH₂OH,CH₃CH₂OCH₃.

Question

Quizplus · Accepted Answer

The boiling point increases with the strength of intermolecular forces. CH₃CH₂OCH₃ is an ether with weaker dipole-dipole interactions, while CH₃CH₂OH and CH₃CH₂CH₂OH are alcohols with stronger hydrogen bonding. Among the alcohols, CH₃CH₂CH₂OH has a higher boiling point due to its larger size and increased van der Waals forces.
