Question

Which among the following is a trihydric alcohol?

• A. Ethanol
• B. Glycerol
• C. Ethylene Glycol
• D. Phenol

Answer 1

The Correct Option is B

• Glycerol (also known as glycerin) is a trihydric alcohol because it contains three hydroxyl (–OH) groups.
• Ethanol (Option A) is a monohydric alcohol, containing one hydroxyl group.
• Ethylene Glycol (Option C) is a dihydric alcohol, containing two hydroxyl groups.
• Phenol (Option D) is an aromatic compound with one hydroxyl group, but it is not classified as an alcohol.

So, glycerol is the trihydric alcohol in this case.

Answer 2

Glycerol (CHO) is a trihydric alcohol, containing three hydroxyl (-OH) groups attached to carbon atoms. The presence of these hydroxyl groups gives it high affinity for water, making it useful in applications such as cosmetics and pharmaceuticals.
