Explain why an organic liquld vaporizes at a temperature below its bolling point in Its steam distillation.

Explanation

In steam distillation the liquid boils when the sum of vapour pressures due to the orginic liquid `(P_(1))` and that due to water `( P_(2))` becomes equal to the atmospheric pressure `(P) ` i.e.,` P = P _(1) + P _(2).`
`therefore P _(1)` is lower that P the organic liquid vaporises at lower temperature than it.s boiling point.
