FAQs on Flashcards for JEE Chemistry - Alcohols, Phenols and Ethers Class 12

1. What is the difference between alcohols, phenols, and ethers?
Ans. Alcohols, phenols, and ethers are organic compounds that contain oxygen. The main difference between them lies in the presence and arrangement of functional groups. Alcohols have a hydroxyl (-OH) group attached to a carbon atom, while phenols have the hydroxyl group directly attached to an aromatic ring. Ethers, on the other hand, have an oxygen atom bonded to two alkyl or aryl groups.
2. How do alcohols, phenols, and ethers differ in their physical properties?
Ans. Alcohols, phenols, and ethers exhibit distinct physical properties due to their varying molecular structures. Alcohols and phenols can form hydrogen bonds, resulting in higher boiling points compared to ethers. Alcohols and phenols are also soluble in water due to their ability to form hydrogen bonds with water molecules, while ethers are generally less soluble in water.
3. What are the common uses of alcohols, phenols, and ethers?
Ans. Alcohols, phenols, and ethers find various applications in different industries. Alcohols, such as ethanol, are widely used as solvents, disinfectants, and fuel additives. Phenols are commonly used in the production of plastics, pharmaceuticals, and antiseptics. Ethers, like diethyl ether, are used as solvents and in some laboratory procedures.
4. How are alcohols, phenols, and ethers classified?
Ans. Alcohols are classified based on the number of hydroxyl (-OH) groups attached to the carbon atom. They can be classified as primary (one -OH group), secondary (two -OH groups), or tertiary (three -OH groups) alcohols. Phenols, being derivatives of benzene, are classified based on the position of the hydroxyl group on the aromatic ring. Ethers are classified based on the alkyl or aryl groups attached to the oxygen atom.
5. Are alcohols, phenols, and ethers hazardous to health?
Ans. The hazard level of alcohols, phenols, and ethers varies depending on the specific compound and concentration. Some alcohols, such as methanol, can be toxic if ingested or inhaled in high amounts. Phenols can be corrosive and harmful if they come into contact with the skin or eyes. Ethers, like diethyl ether, are flammable and can cause drowsiness or dizziness if inhaled. It is important to handle these compounds with proper safety precautions and follow recommended guidelines.
