The fragrnance of flower is due to the presence of some steam volatile organic compounds called essential oils. These are generally insoluble in water at room temperature but are miscrible with water vapour in vapour phase. A suitable method for the extraction of these oils from the flower is

A

Distillation

B

Crystallisation

C

Distillation under reduced pressure

D

Steam distillation

Text Solution

Verified by Experts

The correct Answer is:
D
Substances (i.e., essential oils) are insoluble in water and have high vapour pressure at 373 K and hence can be separated by steam distillation.
