WebDec 17, 2016 · Cis isomers being unsymmetrical will almost always have a net dipole moment, as opposed to trans isomers where the symmetric nature cancels out the dipole moment. Therefore they are slightly polar and attract each other. Therefore cis isomers have a higher boiling point Edit: I don't know why isobutene has a higher melting point. … WebIn contrast, the cis isomer is a polar molecule with a higher boiling point (60 o C vs 48 o C ) because of the net molecular dipole moment and intermolecular dipole-dipole interactions. These are all interesting and each concept here deserves a separate post, which are right here to go over!
