Aniline involves an amine, which is a Choose... functional group. When an aqueous acid solution is added to an organic solution including aniline, the aniline appears in the Choose... layer in its Choose... form. Then, a base is added to Choose... the aniline.

Basic

Aqueous

Protonated

Reconstitute

Explanation:

Aniline contains the -NH2 group in which the hydrogen atom bears a lone pair of electrons which is capable of accepting a proton hence aniline is basic.

This lone pair makes it possible for aniline to be protonated to yield an ionic substance which enters into the aqueous phase.

Addition of a base leads to the reconstitution of the aniline.

The answer is C.chlorophyll
