Explain, why an organic liquid vaporises at a temperature below its boiling point in its steam distillation?
Options
- ASteam distillation involves the use of superheated steam, which raises the temperature of the organic liquid a
- BThe addition of steam to the organic liquid provides extra heat energy, allowing it to vaporize at a temperatu
- CIn steam distillation, the organic liquid starts to boil when the sum of vapour pressure due to the organic li
- DOrganic liquids always vaporize below their boiling points when subjected to steam distillation due to the uni
Correct answer
C. In steam distillation, the organic liquid starts to boil when the sum of vapour pressure due to the organic li
Step-by-step solution
Correct Option is : (C) In steam distillation, the organic liquid starts to boil when the sum of vapour pressure due to the organic liquid (P 1 ) and the vapour pressure due to water P 2 becomes equal to atmospheric pressure (P), that is, P=P 1 +P 2 .Since P 1 2 ,organic liquid will vaporise at a lower temperature than its boiling point.
