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. crypto loopringWebAlkenes are used to make polymers such as polystyrene and PVC, and can also be found in products such as antifreeze and paints.
