Heads up ghost11, homework questions are against the TOS you agreed to here on SDN and the admins are typically quite merciless about it.

This is a pre-dental forum, not a place to ask questions about your school work.

Acid-Base Separation homie

1) add HCl to extract aminobenzoate -- drain aqueous layer -- once separated, add some NH4OH until it gets basic -- ether extraction from the water --> aminobenzoate.
2) leaves you with dibromobenzene and phenanthrene in the organic layer.
3) fractional distillation

You'll probably get a better answer in the DAT discussion.
