Final answer:
Ethers have lower boiling points than alcohols due to the absence of hydrogen bonding.
Step-by-step explanation:
Ethers have lower boiling points than alcohols because they lack the OH group, which allows alcohols to engage in hydrogen bonding. In contrast, ethers do not have hydrogen atoms that can form hydrogen bonds with each other. This weaker intermolecular force results in lower boiling points for ethers.
