4. Look at the structure of the product (provided), 3 hydrogens are labelled (H₁, H₂ and H.). While H₂ may look simple on the ¹H NMR spectrum that you obtained (due to low resolution), it actually has a more complex splitting pattern. Create a tree diagram showing the splitting of H₁. Hint: H₁ is diastereotopic proton, assume JAB > Jac and assume no long range (>3 bond) coupling. AC Hb Ha I Hc
