Properties of poly chloroethene

WebIn this case, the second intermediate is more stable because of resonance: a lone pair of electrons on the Cl can be delocalized into the vacant p orbital on the C. This is not ideal, because it puts a + charge on the Cl. But to the extent that it happens, it lowers the energy of the intermediate.
