An excess of alcohol at a low temperature in the presenceof conc. H₂SO₄ produces an:
Correct answer: A. Ether
- A. Ether
- B. Organic acid
- C. Ester
- D. Alkene
Explanation
The acid-catalyzed dehydration of alcohols can lead to two different products. At low temperatures (around 140°C) and with an excess of the alcohol, an intermolecular reaction (SN2 mechanism) is favored, leading to the formation of an ether.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
