Can anyone please explain why carbon 1 and carbon 2 are two different environments? I am not really sure which part of the molecule you look at to determine it. Thanks

One is ortho to the -OH, the other is meta. Therefore they are in different environments.

This is just A-level chemistry, so the spec doesn't really require us to know much about meta or ortho. I was told that you just look for the line of symmetry but how?

Ortho means the substituent is next to whatever group you're referring to, meta means it's got one carbon between them and para means they're on opposite sides.

i guess I having more sophisticated answers, thanks, never knew this existed

If you imagine the same molecule but without the OH group, then you can see it has a plane of symmetry running across the molecule, this would make carbons 6 and 7 equivalent, carbons 5 and 8 equivalent, carbons 3 and 4 equivalent and carbons 1 and 2 equivalent. Hopefully that helps you see the sort of symmetry to look for when trying to spot equivalent carbons. Adding the OH means the molecule loses this symmetry so the carbons are no longer equivalent!
