Question:
In steam distillation of toluene, the pressure of toluene in vapour is
In steam distillation of toluene, the pressure of toluene in vapour is
Updated On: May 4, 2024
- Equal pressure of barometer
- Less than pressure of barometer
- Equal to vapour pressure to toluene in simple distillation
- More than vapour pressure of toluene in simple distillation
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The correct option is( B): Less than pressure of barometer.
During the process of steam distillation involving toluene, the vapor pressure of toluene is lower than that indicated by the barometer. This occurs because steam distillation is employed when a solid or liquid substance is immiscible in water, exhibits volatility when exposed to steam, while the impurities in question remain non-volatile.

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024

Concepts Used:
Purification of Organic Compounds
We commonly use these methods for the purification of substances:
- Simple crystallization - The most common method that we use to purify organic solids.
- Fractional crystallization - It is the process of separation of different components of a mixture by repeated crystallisations.
- Sublimation - Certain organic solids on heating directly change from solid to vapor state without passing through a liquid state. These substances are sublimable. This process is sublimation.
- Simple distillation - It is the joint process of vaporization and condensation.
- Fractional distillation - It is the process to separate a mixture of two or more miscible liquids which have boiling points close to each other
- Distillation under reduced pressure
- Steam distillation
- Azeotropic distillation
- Chromatography
