A steam volatile organic compound which is immiscible with water has a boiling point of 250°C. During steam distillation, a mixture of this organic compound and water will boil:
A
above 100°C but below 250°C
B
above 250°C
C
at 250°C
D
close to but below 100°C
Detailed Solution
In steam distillation of an immiscible mixture, the combined vapour pressure of water and the organic compound equals atmospheric pressure at a temperature below the boiling point of either pure component, i.e. close to but below 100°C.
