Question

When isolating fluorenone from your organic layer, you will use a drying agent:

	A	because the ether has seen water and is considered wet.
	B	to get rid of residual benzoic acid.
	C	to get rid of salts.
	D	none of the above.

Answer 1

When isolating fluorenone from your organic layer, you will use a drying agent:

WE typically use drying agents for water in order to avoid water/moisture in our sample

Therefore, the reasn should be:

A) because the ether has seen water and is considered wet.

Since this is an extraction

drying agent will not interact with the salts

and th ebenzoic acid is not considered a "wet" specie. So the drying agent will not interfere

Also note that the benzoic acid is our organic layer
