5) What are the coupling patterns and approximate coupling constants for the explicitly shown hydrogen atoms of the following carbohydrate? Note: Hydrogen atoms attached to the aromatic ring show $${}^3\mathrm{J}$$ and $${}^4\mathrm{J}$$ coupling (long range coupling), but the methyl group is not involved in any allylic coupling.
