Which of the following is structure of a separating funnel?
The Correct Option is A
Solution and Explanation
The diagram is option (A) clearly represents separating funnel which is used to separate two Liquids that don't mix or are not soluble in each other.
So, the correct option is (A).

Top JEE Main Questions
- In a hydrogen like atom, when an electron jumps from the $M$ - shell to the $L$ - shell, the wavelength of emitted radiation is $\lambda$. If an electron jumps from $N$-shell to the $L$-shell, the wavelength of emitted radiation will be :
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:

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
