Question
Chapter 6, Problem 4Q
Interpretation Introduction
Interpretation:
The molecular weight of the unknown compound is to be determined.
Concept introduction:
Steam distillation is used to extract and purify the temperature-sensitive compounds. Steam distillation is generally used for organic compounds that are sensitive to temperature. The advantage of steam distillation is that the temperature-sensitive compounds can be boiled and extracted at a lower temperature without decomposition.
