6. The index of an NMR spectrum for a compound with molecular formula C9H12O2 is given : 1H NMR (300 MHz, CDCl3) δ 6.93 (dd, J = 8.6, 7.9 Hz, 1H), 6.75 (dd, J = 7.9, 2.8 Hz, 1H), 6.74 (dd, J = 8.6, 2.8 Hz, 1H), 3.82 (s, 3H), 3.78 (s, 3H), 2.27 (s, 3H). Extra information: For C9H12O2 , there must be either 4 double bonds, or 3 double bonds and a ring, or 2 triple bonds to account for the unsaturation.
