WebCorrect. You want to form the more stable intermediate.You have a choice between (+)CH2-CH2Cl and CH3-C (+)HCl. In 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. flury arzt bettlachWebApr 3, 2024 · polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers.
