NEET · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
On heating, some solid substances change from solid to vapour state without passing through liquid state. The technique used for the purification of such solid substances based on the above principle is known as
- A Sublimation
- B Distillation
- C Chromatography
- D Crystallization
Answer & Solution
Correct Answer
(A) Sublimation
Step-by-step Solution
Detailed explanation
(\(1\)) Sublimation : It is the purification technique based on principle that on heating, some solid substances change from solid to vapour state without passing through liquid state. (\(2\)) Distillation : It is used to separate volatile liquids from non-volatile impurities and the liquids having sufficient difference in their boiling point.
