Question

For fractional distillation, the difference in their boiling points should be ___________​

Answer 1

104 degrees Fahrenheit

When the boiling points of the two liquids in the mixture are close, generally a difference of less than 40 degrees Celsius (104 degrees Fahrenheit), fractional distillation is more efficient.

Answer 2

difference should be 40⁰c

Explanation:

for that the difference should be at least 4⁰c or more.

Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.
