organic chemistry - What is the order of the following compounds based on polarity?

What is the order of the following compounds from more polar to less polar?

• Hydrochloric acid,


• Methanol,


• Hexane,


• Petroleum benzene

I know that $\ce{HCl}$ has the largest polarity. Hexane I guess has the less. I guess the order should be like:
$\ce{HCl}$ > Methanol > Petroleum benzene > Hexane

Is this correct? I'm not sure of the place of petroleum benzene.
