How do I calculate the ¹ proton Chemical shift for the hydrogen forming a phenol for the attached compound? I have this book, Introduction to Spectroscopy by Donald L. Pavia. In table A6.1 the constant value for a hydrogen bonded to an oxygen is 2.56 and 1.85 for a mon. sub. benzene ring, but this is a disubstituted ring, I am not sure of the proper constant when the formula for the ring is C6H4 and and not C6H5.

What should I simplify in order for you master and ph.d chemists to help me? By the way, the ring is meta-substituted.

Well two things:
If you can't even get the structure correct who do you expect us to help with accurate information?
And, we don't give answers here, you need to show your attempts.

Start by looking for another table in your book for di-substituted aromatic rings.
