Alcohols, Phenols, and Ether JEE Notes, Download PDF

Alcohols, Phenols, and Ether JEE Notes: These are key functional groups in organic chemistry, frequently tested in JEE exams. Alcohols contain hydroxyl (-OH) groups, phenols have -OH attached to aromatic rings, and ethers feature an oxygen atom linked to two alkyl or aryl groups. These compounds exhibit distinct physical and chemical properties such as hydrogen bonding, acidity, and substitution reactions.  

These notes help students perform better in their exams by helping them learn all the important formulas and reactions. Important reactions include oxidation, dehydration, Williamson Ether Synthesis, Kolbe’s, and Reimer–Tiemann reactions. Preparing these Alcohols, Phenols, and Ether JEE Notes helps students understand mechanisms, guess products, and strengthen problem-solving skills important for scoring high in JEE Main and Advanced.

Alcohols, Phenols, and Ether Important Questions JEE

Check below for the Practice Questions from Alcohols, Phenols, and Ether JEE Notes made to strengthen your understanding of key reactions and mechanisms. 

These Alcohols, Phenols, and Ether solved examples JEE help students apply theoretical concepts, test problem-solving skills, and prepare effectively for both JEE Main and Advanced examinations through practical, exam-oriented practice.

1. How can ethanol be prepared from ethene? Give a reason with a reaction.
Answer: By acid-catalyzed hydration of ethene using concentrated H₂SO₄ followed by hydrolysis:
CH₂=CH₂ + H₂O → CH₃CH₂OH.

2. What is the product when phenol reacts with bromine water?
Answer: 2,4,6-tribromophenol is formed as a white precipitate.

3. What happens when phenol reacts with chloroform and NaOH?
Answer: Salicylaldehyde is formed — this is the Reimer–Tiemann reaction.

4. Write the IUPAC name of CH₃–CH₂–O–CH₂–CH₃.
Answer: Ethoxyethane (common name: diethyl ether).

5. What is formed when ethanol is oxidized with acidified potassium dichromate?
Answer: Ethanol oxidizes to ethanal, and further oxidation gives ethanoic acid.

6. What is the mechanism involved in the Williamson Ether Synthesis?
Answer: The reaction proceeds via an SN2 mechanism between an alkoxide ion and an alkyl halide.

7. Why do alcohols have higher boiling points than ethers and alkanes of comparable molecular masses?
Answer: Due to intermolecular hydrogen bonding among alcohol molecules.

8. What is the product formed when phenol reacts with dilute nitric acid?
Answer: A mixture of o-nitrophenol and p-nitrophenol is formed.

9. Write the reaction of dehydration of ethanol.
Answer: CH₃CH₂OH → CH₂=CH₂ + H₂O (in presence of concentrated H₂SO₄ and heat).

10. Which compound is more acidic — ethanol or phenol? Why?
Answer: Phenol is more acidic because the phenoxide ion formed after losing a proton is resonance-stabilized, unlike the alkoxide ion from ethanol.
