“12th Class Chemistry Chapter 11: Alcohols, Phenols, and Ethers” is a comprehensive outline of the structure, properties, and reactivity of these essential classes of organic compounds. Alcohols, phenols, and ethers are studied in detail because of their widespread applications in industries such as pharmaceuticals, cosmetics, and chemical synthesis. This chapter reveals their functional groups, preparation methods, and their chemical behavior. Improve your understanding with our MDCAT Quiz and free flashcards designed specifically for this subject mastery.
Alcohols and Phenols: Structure and Reactions
Alcohols contain the hydroxyl (-OH) functional group attached to a saturated carbon atom. They are classified as primary, secondary, or tertiary based on the carbon atom bonded to the hydroxyl group. Common examples include ethanol and methanol. Alcohols are known for their hydrogen bonding, which affects their boiling points and solubility.
Phenols contain an -OH group directly attached to an aromatic ring. Such a structure provides phenols with acidic properties, making them entirely different from alcohols. Phenols are being used in disinfectants and antiseptics and for the manufacture of plastics.
Both alcohols and phenols undergo reactions such as oxidation, esterification, and dehydration. Oxidation of alcohols leads to aldehydes, ketones, or carboxylic acids depending on the reaction conditions, while phenols undergo electrophilic substitution reactions like nitration and halogenation.
Ethers: Structure and Applications
Ethers are compounds in which an oxygen atom is bonded to two alkyl or aryl groups. Their general formula is

represent alkyl or aryl groups. Ethers are relatively inert and nonpolar, which makes them good solvents in organic reactions. Diethyl ether, for example, is a common solvent and anesthetic.
Ethers can be prepared by the dehydration of alcohols or by the Williamson synthesis. In general, ethers are much less reactive than alcohols and phenols; however, in acidic media, ethers may be cleaved.
