**Glycerol** (propane-1,2,3-triol) is classified as:
AMonohydric alcohol
BDihydric alcohol
CTrihydric alcohol (three –OH groups)
DPhenol
Answer & Solution
Correct answer: C. Trihydric alcohol (three –OH groups)
Glycerol: CH₂(OH)-CH(OH)-CH₂(OH) — three hydroxyl groups ⇒ trihydric alcohol. Used in soap, cosmetics, food (humectant), explosives (nitroglycerine).
