please answer a b and c. thanks

1. (a) Assign the non-aromatic protons by filling out the table below: BH EH HE HJ N-CH31 HACH3H AH O H DH CH KO Assignment Multiplicity 5.95 (2H) 3.48 (1H) 2.95 (1H) 2.83 (1H) 2.70 (3H) 1.27 (3H) Hint: Assume no coupling to N-H protons (b) Ho has 5 6.78. Explain why its multiplicity is a doublet of doublets (dd). (c) Which protons do 6.84 (s) and 5 6.88 (d) (s correspond to
