ChemistryIntermolecular forcesASOCR Created by: Polaris03Created on: 09-02-20 21:46 What is the product of the reaction of bromine and ethene? 1,2-dibromoethane 1 of 8 Where in the ethene molecule has the density of negative charge the highest? The double bond 2 of 8 What does the high density of negative charge in the ethene molecule cause? Repulsion of electrons in the bromine molecule - bromine becomes a polar molecule 3 of 8 What happens due to the polarity of the bromine molecule? The bonding becomes weaker so the bond between the 2 bromine atoms breaks - free bromide ion takes away both electrons as a lone pair 4 of 8 What happens to the bromine atom that is positively polar? It accepts a bonding pair of electrons from the ethene double bond, forming a covalent (dative) bond 5 of 8 The ethene molecule becomes a positively charged ion, what happens next? A covalent bond forms between the carbocation and the bromide ion 6 of 8 What is a molecule called when it becomes polar? Dipolar 7 of 8 What do curly arrows show? The movement of electron(s) from tail to tip 8 of 8
