Grade 12th passOrganic ChemistryWhen ethene is treated with Br2 in presence of NaCl it gives Anbreen farooqi 8 Years agoGrade 12th pass
Arun8 Years agoTreatment of alkenes with bromine (Br2) gives vicinal dibromides (1,2-dibromides) hence CH2 = CH2 + Br2 – – – – – → CH2Br – CH2Br
Harshit Panwar8 Years agoSince ethene is an alkene so it have double bonds.Here Be breaks the bonds between ethene.Chemical equation :--CH2 = CH2 + Br2 -------> CH2Br - CH2BrHope it helps you.
