Hydrogen and bromine reaction
WebThe mechanism of electrophilic addition of bromine molecule to an alkene (ethene) double bond can be presented in two steps: Alkene as an electron rich molecule so therefore reacts with electrophile. Under the influence of pi electrons in the double bond, stronger polarization of the atomic bond in the bromine molecule occurs. WebReaction of chromium with halogens. Chromium reacts directly with fluorine, F 2, at 400°C and 200-300 atmospheres to form chromium (VI) fluoride, CrF 6. Under milder conditions, chromium (V) fluoride, CrF 5, is formed. Under still milder conditions, chromium metal reacts with the halogens fluorine, F 2, chlorine, Cl 2, bromine, Br 2, and ...
