Question

When the boiling point between the components in the liquid mixture is less than 25°C, then fractional distillation is used.

• A. True
• B. False

Answer 1

The correct option is A True

1. Fractional distillation: The process of separation of two or more miscible liquids with a difference in their boiling points close to each other $\left(25\mathrm{k}\right)$ into individual components.
2. The process of separating volatile components (with different boiling points), which have a difference of less than $25\mathrm{k}$ of a mixture (such as crude oil) by heating the mixture in a column and collecting and condensing the vapour drawn at different levels of the column.

Therefore, the given statement is true.
