Final answer:
The boiling point of a mixture of eugenol and water at atmospheric pressure will vary depending on the ratio of the two components.
Step-by-step explanation:
The boiling point of a mixture of eugenol and water at atmospheric pressure will vary depending on the ratio of the two components. Eugenol has a boiling point of 248-252 °C, while water has a boiling point of 100 °C. When the two substances are co-distilled, the resulting boiling point will be somewhere between these two temperatures, depending on the proportions of eugenol and water.
