Alcohols Phenols and Ethers
Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon aliphatic and aromatic respectively is replaced by –OH group These classes of compounds |
In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups.
They have the general formula R−O−R′, where R and R′ represent the alkyl or aryl groups.
What is the classification of alcohol and phenols?
On the basis of the number of functional groups, alcohol and phenols are classified as mono-,di-, tri or polyhydric alcohol and phenols.
For monohydric alcohols/phenols they contain one -OH group, for dihydric alcohols/phenols they contain two -OH groups, for tertiary alcohols three carbon atoms are directly attached.
What is the classification of alcohol?
Alcohols are classified as primary, secondary or tertiary alcohols.
The classification is done in accordance with the carbon atom of an alkyl group is attached to the hydroxyl group.
Most of the alcohols are known to be colourless liquids or even are said to behave as solid at room temperatures.
What is the classification of ethers?
The classification of ethers examples can be of two types, symmetrical ethers, also known as simple ethers, and unsymmetrical ethers, also known as mixed ethers.
We have further discussed the properties of Ethers and the difference between Alcohol and Ether.
