Assertion-Reason Type Question:

Assertion: A mixture of acetone and methanol can be separated by fractional distillation.

Reason: The difference between their boiling points is very less.

Explanation:

  • Acetone and methanol are two different liquids that have very similar boiling points.

  • The boiling point of acetone is 56.05°C, and the boiling point of methanol is 64.7°C.

  • Although the difference between the boiling points of acetone and methanol is very less, it is still possible to separate them by fractional distillation.

  • Fractional distillation is a process that separates the components of a mixture based on their boiling points.

  • In fractional distillation, the mixture is heated, and the vapors that are produced are condensed and collected separately.

  • Since the boiling points of acetone and methanol are slightly different, the vapor produced by each liquid will have a slightly different composition.

  • This difference in composition can be exploited to separate the two liquids by fractional distillation.

  • Thus, it is true that a mixture of acetone and methanol can be separated by fractional distillation.

  • The reason given is also correct as the difference between the boiling points of acetone and methanol is very less, which makes it possible to separate them by fractional distillation.

  • Therefore, option (A) is the correct answer.



Conclusion:

Hence, we can conclude that a mixture of acetone and methanol can be separated by fractional distillation, and the reason given is also correct as the difference between their boiling points is very less.
