The Correct Option isB
Solution and Explanation
Step 1: Understanding fractional distillation.
Fractional distillation is a technique used to separate mixtures based on differences in their boiling points. In this process, the component with a lower boiling point will vaporize first, and the component with a higher boiling point will condense later in the distillation column.
Step 2: Analyzing Statement I.
Statement I is correct. During fractional distillation, the substance with a higher boiling point does not condense first. Instead, the substance with the lower boiling point will vaporize first and condense at the top of the column. The substance with a higher boiling point will condense later.
Step 3: Analyzing Statement II.
Statement II is incorrect. In a fractionating column, the substance with the higher boiling point tends to stay concentrated at the bottom of the column, not at the top. As the vapor rises up the column, it cools and condenses, with components having lower boiling points being more concentrated at the top.
Step 4: Conclusion.
Statement I is correct, while Statement II is incorrect.
Final Answer: Statement I is correct but Statement II is incorrect.
