FAQs on Mnemonics: Alcohols, Phenols and Ethers - Chemistry Class 12 - NEET

1. What are the main differences between alcohols, phenols, and ethers?
Ans.Alcohols are organic compounds with one or more hydroxyl (-OH) groups attached to a carbon atom, phenols contain a hydroxyl group directly bonded to an aromatic hydrocarbon ring, and ethers consist of an oxygen atom connected to two alkyl or aryl groups. These differences affect their chemical properties and reactivity.
2. How can I memorize the structures of alcohols, phenols, and ethers for the NEET exam?
Ans.A useful mnemonic could be "A PEACEful OCEAN": A for Alcohols, P for Phenols, E for Ethers, C for Carbon, and O for Oxygen. Visualizing the structures alongside this mnemonic can help reinforce memory retention.
3. What are some common uses of alcohols, phenols, and ethers in everyday life?
Ans.Alcohols are often used as solvents and in the production of alcoholic beverages, phenols are used in antiseptics and plastics, while ethers are commonly utilized as solvents in laboratories and in the production of pharmaceuticals.
4. What are the safety precautions to consider when handling alcohols, phenols, and ethers?
Ans.It is important to handle these compounds in well-ventilated areas, wear appropriate personal protective equipment (PPE) such as gloves and goggles, and keep them away from open flames or heat sources, as many are flammable or toxic.
5. How do the boiling points of alcohols, phenols, and ethers compare, and why?
Ans.Alcohols generally have higher boiling points than ethers due to hydrogen bonding between alcohol molecules. Phenols also have elevated boiling points due to their ability to form hydrogen bonds, though they are typically lower than those of alcohols. Ethers have lower boiling points since they cannot form hydrogen bonds with each other.
