Question 1

It is a process of separation & purification of liquid organic compounds by selective evaporation & condensation.

Answer 1

Distillation

Question 2

The temperatures at which a liquid distills is a definite value at a given pressure, for every pure organic compound

Answer 2

Boiling Point

Question 3

Types of Distillation

Answer 3

• Simple Distillation
• Vacuum Distillation
• Steam Distillation
• Fractional Distillation
• Reflex

Question 4

This consists of a round-bottomed flask connected by means of a distillation adapter to a water-cooled condenser.

Answer 4

Simple Distillation

Question 5

The vapors generated in the pot rise the fractionating column and encounter cooler surfaces, upon which they condense.

Answer 5

Vacuum Distillation

Question 6

This method is used for the separation of water immiscible compound of low volatility from non- volatile tarry products which are formed as by-products in many reactions.

Answer 6

Steam Distillation

Question 7

It is used to separate mixtures in which the components have boiling points that differ by only a few degrees, by employing a fractionating column in the distillation apparatus.

Answer 7

Fractional Distillation

Question 8

Reflex is a distillation technique involves the condensation of vapors & the return of this condensate to the system from which it originated.

Answer 8

Reflex Distillation
