Crystallisation -

It is based on solublity of  compounds.

- wherein

The impure compound is dissolved in solvent and heated at high temperature, on cooling the hot solution pure compounds crystallises.

 

 

 

Steam Distillation -

This method is used to separate substances which are steam volatile and are immiscible with water.

- wherein

e.g.   O-nitrophenol and P-nitrophenol

H_{2}O: sugar → Recrystallization

H_{2}O: Aniline →Steam distillation

H_{2}O: Toluene → Differential extraction

 

 


Option 1)

(A)\rightarrow (S); (B)\rightarrow (R);(C)\rightarrow (P)

 

Option 2)

(A)\rightarrow (Q); (B)\rightarrow (R);(C)\rightarrow (P)

Option 3)

(A)\rightarrow (R); (B)\rightarrow (P);(C)\rightarrow (S)

Option 4)

(A)\rightarrow (Q); (B)\rightarrow (R);(C)\rightarrow (S)
