Transcribed Image Text:### Distillation of Ethyl Acetate and Ethyl Butyrate
**Problem 4:**
A 1:1 mixture of ethyl acetate and ethyl butyrate can be efficiently separated by careful distillation. Answer the following questions about this distillation. Hint: It’ll help to look up boiling points (again).
#### a. Concentration in Early Fractions
Which of the two compounds is in higher concentration in the earlier fractions of distillate produced in this distillation? Explain why.
*Explanation:* During distillation, the component with the lower boiling point will vaporize first and thus be in higher concentration in the early fractions. By examining the boiling points of ethyl acetate and ethyl butyrate, one can determine which one will distill first.
#### b. Temperature of Vapor at the End
Near the end of a successful distillation, what will the temperature of the vapor above the flask being heated be? How do you know this?
*Explanation:* At the end of the distillation, the temperature of the vapor corresponds to the boiling point of the component with the higher boiling point remaining in the solution. This temperature can be confirmed by referring to the known boiling points of the compounds involved.
