There is a singlet at 1.5 ppm that integrates to 9.16 (major isomer) and another singlet at 1.45 ppm integrating to 0.86 (minor isomer). The ratio of these two peaks also corresponds to the E/Z ratio already determined. In this case it is … TīmeklisIn the first isomer, the higher priority groups are on opposite sides of the bond. That must be the (E)- isomer. The other one, with the higher priority groups on the same side, is the (Z)- isomer. This adds the slight complication that you haven't got a single atom attached to the double bond, but a group of atoms.
