FAQs on Question Bank (Solutions): Alcohols, Phenols & Ethers - Chemistry Class 12 - NEET

1. What are alcohols, phenols, and ethers?
Ans. Alcohols, phenols, and ethers are organic compounds that contain oxygen. Alcohols have a hydroxyl (-OH) functional group attached to a carbon atom, phenols have a hydroxyl group attached to a benzene ring, and ethers have an oxygen atom bonded to two carbon atoms.
2. How are alcohols, phenols, and ethers classified?
Ans. Alcohols are classified based on the number of hydroxyl groups attached to the carbon atom. They can be classified as primary, secondary, or tertiary alcohols. Phenols are classified based on the number and position of hydroxyl groups attached to the benzene ring. Ethers are classified based on the groups attached to the oxygen atom.
3. What are the properties of alcohols, phenols, and ethers?
Ans. Alcohols have a characteristic odor, are soluble in water due to hydrogen bonding, and can undergo reactions such as oxidation and esterification. Phenols are acidic in nature, have higher boiling points than alcohols, and can undergo reactions such as substitution and oxidation. Ethers have low boiling points, are relatively unreactive, and are commonly used as solvents.
4. How are alcohols, phenols, and ethers named?
Ans. Alcohols are named by replacing the -e ending of the corresponding alkane with -ol. The position of the hydroxyl group is indicated by the number of the carbon atom to which it is attached. Phenols are named as derivatives of benzene, with the hydroxyl group indicated by the position number. Ethers are named by identifying the two alkyl groups bonded to the oxygen atom and adding the word "ether".
5. What are some important uses of alcohols, phenols, and ethers?
Ans. Alcohols are used as solvents, antiseptics, and in the production of alcoholic beverages. Phenols are used in the production of plastics, disinfectants, and pharmaceuticals. Ethers are commonly used as solvents, fuel additives, and in the production of perfumes and flavors.
