Match each proton NMR spectrum with isomeric structure that best fits. Be careful: the spectrometer frequencies are not he same, pay attention to the multiplicities and coupling constants which are provided for each spectrum. 6.10(1H,dq,J=1.7;1.0Hz)5.54(1H,dq,J=1.7;1.6Hz)4.20(2H,q,J=7.1Hz)1.94(3H,dd,J=1.6;1.0Hz)1.30(3H,t,J=7.1Hz) B. 7.29(1H,dd,J=13;7.6Hz)4.88(1H,dd,J=13;1.6Hz)4.56(1H,dd,J=7.6;1.6Hz)2.37(2H,t,J=7.2Hz)1.69(2H,6lines,J=7.2;6.9Hz)0.98(3H,t,J=6.9Hz) 4.56(2H,q,J=6.5Hz)4.16(2H,s)1.44(6H,d,J=6.5Hz) 4.56(2H,q,J=6.5Hz)4.16(2H,s)1.44(6H,d,J=6.5Hz)
