Solution
Correct Answer:
Immiscible with water and volatile in steam
Steam distillation is applied to compounds that are immiscible with water but possess appreciable vapour pressure at the boiling temperature of water. Such compounds co-distil with water at a temperature lower than their normal boiling point, preventing thermal decomposition.
This medium difficulty chemistry question is from the chapter purification and characterisation of organic compounds, covering the topic of steam distillation. It appeared in the 2025 exam.
