Question

Assertion (A): Fractional distillation involves distillation and collection of fractions of different liquids boiling at different temperatures.​

Reason (R): It can be used to used to separate liquids which have large boiling point difference. ​

Choose the correct option:

• A. Both A and R are true, but R is not​ the correct explanation of A.
• B. Both A and R are false.
• C. A is true but R is false.
• D. Both A and R are true, and R is​ the correct explanation of A.

Answer 1

The correct option is C A is true but R is false.

• Fractional distillation is the separation of a mixture into its component or fractions.

So Assertion is true.

• It is used to separate a mixture of miscible liquids which have a boiling point difference of less than 25 °C.

So Reason is false.
