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

Which purification method is suitable for a liquid that decomposes upon boiling?

1. Fractional distillation  
2. Steam distillation
3. Simple distillation 
4. Distillation under reduced pressure

Halogen in an organic compound that can be detected by -

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

During steam distillation, an organic compound vaporizes when the total vapor pressure of the immiscible mixture (organic compound + water) equals the ambient pressure. This process causes the organic compound to vaporize at a temperature that is:

1. The same as its normal boiling point.

2. Lower than its normal boiling point.

3. Higher than its normal boiling point.

4. Independent of its normal boiling point.
