Nitrobenzene (boiling point = 210.6°C) is steam distilled at 1 atm pressure. Nitrobenzene will distil off _______________ °C?
Correct answer: A. At < 100
- A. At < 100
- B. At > 210.6
- C. Between 100 and 210
- D. None of these
Explanation
Immiscible liquids boil when the sum of their vapour pressures reaches atmospheric pressure. Water supplies most of this pressure before nitrobenzene reaches its normal boiling point, so the mixture distils below 100°C.
