Question

A mixture of ethanol and methanol are separated by fractional distillation.
This method of separation depends on a difference in property X of these two alcohols.
What is property X?
A boiling point
B colour
C melting point
D solubility

Answer 1

Answer:

The property X is boiling point.

Explanation:

Fractional distillation : The process is used to separate two liquids with different boiling points. The component with lower boiling point evaporates first and passes through the fractionating column. During this journey, it loses its energy and is siphoned to the other column which drains it to another vessel.

The other component with higher boiling point is left in the vessel. In this way, both the components of the solution are separated. So, the method of separation depends on the difference in the boiling point of the liquids.

So, the correct option is A.
