FAQs on Alcohols, Phenols & Ethers in One Shot (NCERT) - 1 Video Lecture - Chemistry Class 12 - NEET
| 1. What are alcohols, phenols, and ethers? |  |
Ans. Alcohols, phenols, and ethers are classes of organic compounds. Alcohols are organic compounds that contain a hydroxyl group (-OH) attached to a carbon atom. Phenols are compounds that have a hydroxyl group attached directly to an aromatic ring. Ethers are organic compounds that have an oxygen atom bonded to two alkyl or aryl groups.
| 2. What are the differences between alcohols, phenols, and ethers? | |
Ans. The main difference between alcohols, phenols, and ethers lies in the presence and position of the hydroxyl group (-OH). Alcohols have a hydroxyl group attached to a carbon atom, phenols have a hydroxyl group attached directly to an aromatic ring, and ethers have an oxygen atom bonded to two alkyl or aryl groups.
| 3. How are alcohols, phenols, and ethers classified? | |
Ans. Alcohols are classified based on the number of hydroxyl groups present. They can be classified as monohydric alcohols (one -OH group), dihydric alcohols (two -OH groups), or polyhydric alcohols (more than two -OH groups). Phenols are classified based on the position of the hydroxyl group on the aromatic ring. They can be classified as ortho, meta, or para-substituted depending on the position of the -OH group. Ethers are classified based on the nature of the alkyl or aryl groups attached to the oxygen atom.
| 4. What are the uses of alcohols, phenols, and ethers? | |
Ans. Alcohols have various uses such as being used as solvents, antiseptics, and fuels. They are also used in the production of alcoholic beverages and as intermediates in the synthesis of organic compounds. Phenols are used in the production of plastics, dyes, and disinfectants. They also find applications in the pharmaceutical industry. Ethers are commonly used as solvents and as intermediates in organic synthesis.
| 5. What are some important reactions of alcohols, phenols, and ethers? | |
Ans. Alcohols undergo various reactions such as oxidation, dehydration, and esterification. Phenols can undergo reactions such as electrophilic substitution, oxidation, and esterification. Ethers are relatively unreactive, but they can participate in reactions such as cleavage of the C-O bond and Williamson ether synthesis.
