Detailed Solution

   The above statement is false.
Polar solvents are soluble in each other. So we cannot separate alcohol dissolved in water by using a separating funnel because both the components are highly soluble in each other due to their polar nature. They can be separated by fractional distillation because there is a difference in the boiling point of alcohol and water. The boiling point of alcohol (78.37) is lower than water (100) .So alcohol will be distilled first by vaporization. The correct statement would be, “We can separate alcohol dissolved in water by fractional distillation”.
