List in order of increasing polarity?
I would expect that the amino phenol is more polar than the phenol. This due to the fact that $\ce{NH2}$ donates electrons to the Benzene ring, making the difference in charge between the Benzene Carbon and the Oxygen stronger.

The Chlorine atom is less electro negative than oxygen (if I'm not mistaken) so that would mean: Naphatlene &lt; Chlorobenzene &lt; Phenol &lt; Amino Phenol.
