Chloroethanol + Benzene --> ???

What is the product of this reaction, I know what it would look like (an OH added to the ethyl group) but what would it be called?

Can you draw the product?

Not quite. Count your carbons.

Oh yeah, my mistake

That looks like the right product. Did your procedure state that 2-chloroethanol was the starting material? (although I would think 1-chloroethanol is unstable)

To name it, you have to remember that the alcohol group will take priority, so the name will end in -ol.

Yeah, it's 2-chloroethanol. I would guess it would be phenyl ethanol but I just want confirmation that it would be 2-phenyl ethanol.

2-phenyl ethanol is the right name. It's because if you don't specify the carbon the phenyl is attached to the name is ambiguous, which defeats the point of systematic names.

Sorry last minute question, it isn't phenyl ethan-2-ol due to OH being the functional group, right?

The -OH group has a higher priority, so the carbon attached to it is automatically labelled 1. Therefore the phenyl is on carbon number 2.
