Suppose an extraction with methylene chloride (d = 1.33 g/mL), also called dichloromethane, is performed with the desired compound initially in brine (d = 1.04 g/mL). In a separatory funnel, which layer will be the organic layer?

Methylene chloride.

Explanation:

Two layers in the separation funnel are the aqueous phase and the organic phase. For solvents lighter than water (i.e., density < 1), the organic phase will rest on top in the separatory funnel, whereas solvents denser than water (density > 1) will sink to the bottom.

Since, methylene chloride is denser than Brine therefore, methylene chloreide sinks at the bottom while methylene chloride stays on top.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
