Question

In fractional distillation, difference in boiling points of components should be:

• A. ${25}^{o}C$
• B. more than ${25}^{o}C$
• C. less than ${25}^{o}C$
• D. less than ${35}^{o}C$

Answer 1

The correct option is C less than ${25}^{o}C$

Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize.

It is a special type of distillation. Generally the component parts boil at less than ${25}^{o}C$ from each other under a pressure of one atmosphere.

Option C is correct.
