Cyclohex-2-enone has two protons on its carbon–carbon double bond (labeled Ha and Hb) and two protons on the carbon adjacent to the double bond (labeled Hc). (a) If Jab = 11 Hz and Jbc = 4 Hz, sketch the splitting pattern observed for each proton on the sp2 hybridized carbons. (b) Despite the fact that Ha is located adjacent to an electron-withdrawing C = O, its absorption occurs upfield from the signal due to Hb (6.0 vs. 7.0 ppm). Offer an explanation.
