Question

Ethers have lower boiling point than their corresponding isomer alcohols because of?

• A. Hydrogen bonding in alcohols that is absent in ether
• B. Hydrogen bonding in ether
• C. Insolubility of ether in water
• D. Inertness of ethers as compared gto alcohols

Answer 1

The correct option is A Hydrogen bonding in alcohols that is absent in ether

Due to the weak polarity in C-O bonds the boiling point of ethers is similar to the alkanes of comparable molecular masses.​
Ether cannot form intermolecular hydrogen bonding due to absence of H attached with the O of ether but in case of alcohol they have -OH which can undergoes intramolecular hydrogen bonding that increases their boiling point. Thus ethers have lower boiling point than their corresponding isomer alcohols because of the Hydrogen bonding in alcohols​.
