Question

Which of the following statements are correct?
A. Glycerol is purified by vacuum distillation because it decomposes at its normal boiling point.
B. Aniline can be purified by steam distillation as aniline is miscible in water.
C. Ethanol can be separated from ethanol water mixture by azeotropic distillation because it forms azeotrope.
D. An organic compound is pure, if mixed M.P. is remained same.

Step 1: Evaluate Statement A

"Glycerol is purified by vacuum distillation because it decomposes at its normal boiling point."

✅ CORRECT — Glycerol (propane-1,2,3-triol) has bp = 290°C but decomposes at that temperature. Distillation under reduced pressure lowers the effective bp (e.g., to ~150°C at ~15 mmHg), allowing purification without decomposition.

Step 2: Evaluate Statement B

"Aniline can be purified by steam distillation as aniline is miscible in water."

❌ INCORRECT — Aniline is immi
