Q. Assertion (A): Benzene (boiling point 353K) and methanol (boiling point 338K) are separated by simple distillation.
Reason (R): Fractional distillation is used to separate two liquids from their mixture when their boiling points differ by `20^@` or so.

Answer

C

Explanation

(A) is correct simple distillation is used to separete two liquids which differ in their boiling points widely. (R) is incorrect because fractional distillation is used to separate two liquids which differ in their boiling points by `10^@C` or so.
