Ethene and hydrogen bromide reaction
WebApr 9, 2016 · Explanation: Ethene and bromine are an addition reaction because ethene is an alkene - it has a double bond. It is easier for new atoms to open the double bond and react there than to remove the hydrogen already attached, and then bond to it, which would be a substitution reaction. Alkenes are more unstable than alkanes, because alkenes … WebNov 5, 2014 · 1 Answer. The mechanism of the addition of hydrogen bromide to ethene is called electrophilic addition. The region of highest electron density in ethene is the double bond, where the π electrons are. Hydrogen bromide acts as an electrophile toward the π electrons of the double bond. The proton of hydrogen bromide is positively polarized …

Web1. The alkene 3-methylpent-2-ene (CH3CH=C (CH3)CH2CH3) reacts with hydrogen bromide to form a mixture of 3-bromo-3-methylpentane and 2-bromo-3-methylpentane. … Because ethene is a symmetrical alkene, there is no effect of adding an organic peroxideto change the location of HBr molecule is added. … See more HBr molecule is polarized because there is a electronegativity difference between hydrogen and bromine atoms. Also, electrons density around the double bond is higher. (due to higher electrons density, those places can be … See more Ethene is an symmetrical alkene with two carbon atoms. With HBr, ethene readily reacts and give ethyl bromide (bromoethane)as the product. See more
