The latest technique for isolation, purification and separation of organic compounds is -

The method that can be used to separate two compounds with different solubilities in a solvent is-
1. Distillation
2. Isolation
3. Fractional crystallization
4. Filtration

Method that can be used to purify the liquid that decomposes on boiling is :

1. Fractional distillation

2. Distillation under reduced pressure

3. Steam distillation

4. Distillation

The purification method based on the difference in solubilities of the compound and the impurities in a solvent is -
1. Crystallisation
2. Distillation
3. Chromatography
4. Isolation
