Classification and Nomenclature of Alcohols, Phenols, and Ethers
In Class 12 Chemistry, the classification of alcohols, phenols, and ethers is based on their structure and the group they are attached to. Alcohols are classified as primary, secondary, or tertiary, depending on the number of alkyl groups attached to the carbon bearing the OH group. Phenols have a hydroxyl group directly attached to an aromatic ring. Ethers have two alkyl or aryl groups attached to an oxygen atom. Nomenclature follows IUPAC guidelines, where priority is given to the longest carbon chain and the functional groups’ position.
Physical Properties of Alcohols, Phenols, and Ethers
The physical properties of these compounds are influenced by the presence of the hydroxyl group in alcohols and phenols and the ether linkage in ethers. Alcohols and phenols usually have higher boiling points due to hydrogen bonding, while ethers have relatively lower boiling points. Solubility in water decreases with increasing molecular weight.
Preparation of Alcohols, Phenols, and Ethers
Alcohols can be prepared by the hydration of alkenes, reduction of aldehydes, ketones, and carboxylic acids. Phenols are commonly prepared by the cumene process or from diazonium salts. Ethers are prepared by the dehydration of alcohols or the Williamson synthesis method.
Chemical Reactions of Alcohols, Phenols, and Ethers
Alcohols undergo reactions like dehydration, oxidation, and esterification. Phenols exhibit acidity and undergo electrophilic substitution reactions. Ethers are relatively less reactive but can undergo cleavage with strong acids.
Important Points to Remember about Alcohols, Phenols, and Ethers
Key points include understanding the functional groups, reaction mechanisms, and physical and chemical properties that differentiate these compounds.
