Question

In the liquid/liquid extraction of chlorophyll (a largely non-polar molecule) with isopropanol/water and vegetable oil, where would the chlorophyll end up? Check all
that apply. EXPLAIN YOUR ANSWER.

A) the bottom layer
B) the vegetable oil, the organic layer
C) the top layer
D) the isopropanol, the aqueous layer

Answer 1

Answer:

A) the bottom layer

Explanation:

This is because oils are non-polar while water is polar. The water molecules are much more attracted to each other than the non-polar oil molecules, so you can mix all you want, but the water molecules will end up next to water molecules again when things settle down.
