How to distinguish 1-chlorohexane (C6H13Cl), chlorobenzene (C6H5Cl) and benzoyl chloride (C6H5COCl) by using chemical tests?

[macman104]

Do you have any limits on what chemical tests you can perform?  Can you give us some thoughts on what you think?  Start by identifying functional groups, and then listing what tests you could perform to identify those functional groups.

For each compound, you want to find a test that will give a positive result for only that compound, and a negative result (or possibly a slower reaction) for the other two.

Or, identify two of them, and then the third one is the one that is left out.
