Question

Steam distillation is applied to those organic compounds which are steam volatile and.
A) Soluble in water.
B) Insoluble in water.
C) Sparingly soluble in water.
D) Insoluble in all solvents.

Answer 1

Hint: We know that steam distillation may be a separation technique that harnesses the low boiling purpose property of immiscible mixtures. It’s predominately accustomed to separate temperature-sensitive organic molecules from a non-volatile contaminant.

Complete answer:
We must have to remember that in steam distillation the organic molecule should be immiscible in water. The immiscible mixture is heated to boiling, inflicting the distillation of each water and also the volatile organic compounds. This implies that the vaporous mixture travels upwards to a condenser that then condenses the vapor to liquid so it will be collected. In distinction to straightforward distillation, steam distillation uses a water reservoir to fill up water within the heated mixture throughout the process. The immiscible organic part is slowly distilled alongside the water, whereas the non-volatile component remains within the heated mixture. Once the organic element is distilled, it'll then be separated from the water exploitation liquid-liquid extraction.
Therefore, option (B) is correct.

Note:
Now we can discuss about the applications as,
Steam distillation is usually used within the isolation of essential oils, to be used in perfumes, for example. During this methodology, steam is more established as the material containing the specified oils.
Eucalyptus oil, oil and orange oil are obtained by this method on an industrial scale. Steam distillation is additionally generally utilized in chemical laboratories together with many substance separation methods.
Steam distillation is also a very important means of separating fatty acids from mixtures and for treating crude merchandise similar to tall oils to extract and separate fatty acids and different commercially valuable organic compounds.
