Make a saturated solution of lithium chloride in methanol by stirring 20 g of the solid with 100 cm3of methanol and filtering the resulting … WebEthene is an symmetrical alkene with two carbon atoms. With HBr, ethene readily reacts and give ethyl bromide (bromoethane) as the product. CH 2 =CH 2 + HBr → CH 3 CH 2 Br HBr molecule is added across the double bond of ethene. In this case, Markovnikov rule is not required because ethene molecule is symmetrical around the double bond.

What type of reaction is ethene with bromine? - KnowledgeBurrow

WebJul 31, 2024 · Ethene and other simple alkenes generally are poor dienophiles and react with 1,3-butadiene only under rather extreme conditions and in low yield. However, when the diene is substituted with several electron-attracting groups such as chlorine or bromine, electron-donating groups on the dienophile facilitate the reaction. WebFor example, ethene reacts with bromine to form 1,2-dibromoethane: CH2=CH2 + Br2 → CH2BrCH2Br It is easier to see what happens using displayed formulae: The reaction is an ‘addition’ reaction... css center align div https://kathrynreeves.com
