a. Preparing drinking water from sea water. b. Separating benzene, bp 80 °C (760 torr), from toluene, bp 111 °C (760 torr). c. Obtaining gasoline from crude oil. d. Removing diethyl ether, bp 35 °C (760 torr), from p-dichlorobenzene (s), mp 174–175 °C
Specify whether a simple distillation or a fractional distillation would be more suitable for each of the following purifications, and briefly justify your choice:
a. Preparing drinking water from sea water.
b. Separating benzene, bp 80 °C (760 torr), from toluene, bp 111 °C (760 torr).
c. Obtaining gasoline from crude oil.
d. Removing diethyl ether, bp 35 °C (760 torr), from p-dichlorobenzene (s), mp 174–175 °C.
Simple distillation and fractional distillation are two techniques used to separate different components of a mixture based on their boiling points.
Simple distillation is used to separate a pure solvent from a solution. This technique involves heating the solution and collecting the vapors that form as the solvent boils. The collected vapors are then condensed back into a liquid, resulting in the separation of the solvent from the other components in the solution.
Fractional distillation, on the other hand, is used to separate two or more components of a mixture that have similar boiling points.
