In the trans isomer on the other hand, this does not occur because the two C−Cl bond moments cancel and the molecule has a net zero dipole (it does however have a non-zero quadrupole).
No isómero trans isto non ocorre porque os momentos de enlace dos dous C-Cl se cancelan e a molécula ten un dipolo neto de cero (pero ten un cuadrupolo que non é cero).
