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.
