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”.
