What is an azeotrope? 2. Under what conditions is it better to perform a steam distillation (instead of, say, a simple distillation)? 3. During a steam distillation, how can you tell if the organic compound is still coming over (i. e., still being distilled)? 4. For this experiment, at the end of the steam distillation, the receiving flask should contain two layers of liquid. What is the chemical identity of these two liquids? 5. What is the purpose of adding 10% sodium carbonate solution to the distillate if it is acidic to litmus?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
