Ethers functional group
Ethers functional group
An oxygen atom connected to two alkyl or aryl groups. (R-O-R')
Why ethers have low boiling points
Why ethers have low boiling points
Ethers lack -OH groups for hydrogen bonding, resulting in only weak dipole-dipole interactions.

Study Notes
Ethers
- The functional group present in ethers is an ether linkage (R-O-R').
- Ethers have low boiling points compared to alcohols of comparable molar mass because they cannot form hydrogen bonds with each other, only with water.
- Diethyl ether was initially used as an anesthetic.
- Diethyl ether is the most widely used compound among ethers.
- In common names for ethers, the two branches connected to the oxygen atom are named as separate words, with the oxygen atom not mentioned.
