Study Notes
Ethers and their properties
- Ethers have low boiling points due to the lack of hydrogen bonding.
- The oxygen atom in an ether doesn't have a hydrogen atom attached to it.
- This means that the only intermolecular forces between ether molecules are weak van der Waals forces.
- These forces are weaker than hydrogen bonds, which means that ethers have lower boiling points than alcohols of comparable molar mass.
Naming ethers
- In the IUPAC system, ethers are named by identifying the two alkyl groups attached to the oxygen atom.
- The two alkyl groups are then listed alphabetically, followed by the word "ether."
- For example, the compound with the formula CH3CH2OCH2CH3 is called diethyl ether.
Uses of ethers
- Diethyl ether and other ethers are primarily used as solvents.
- They are good solvents for many organic compounds and are often used in extractions and reactions.
- Diethyl ether was once used as a general anesthetic, but it has been largely replaced by newer, safer anesthetics.
- Diethyl ether was initially used as an anesthetic due to its quick action and pleasant smell.
Other key properties
- Diethyl ether is colorless.
- Ethers contain the ether functional group, which features an oxygen atom bonded to two alkyl groups.
Consequences of Diethyl Ether's Use
- Diethyl ether is highly flammable and can be explosive in the presence of air.
- It can also cause respiratory irritation and can be toxic in high doses.
- These properties, alongside the introduction of safer anesthetics, contributed to the decline of its use as an anesthetic.
