Question

distillation of cherry-vanilla cola
heat is applied gently to a solution of flat cherry-vanilla cola in a flask that is attached to a condensing tube. when the soda is distilled, the distillates are collected in the following order.

first distillate: vanilla - scented ester
second distillate: cherry - scented ester
third distillate: water
remaining distillate: solid sugar in the original flask

based on the order the substances come out of the distillation, which substance has the highest boiling point?

• the cherry ester
• the vanilla ester
• the water
• the sugar remaining in the flask

Explanation:

In distillation, substances with lower boiling points vaporize and are collected first, while those with higher boiling points remain longer or stay in the flask. The sugar is the last remaining substance, meaning it requires the highest temperature to boil.

Answer:

D. the sugar remaining in the flask
