The radiolytic formation of tetravalent bromine and its reactions with halide ions and halogensThe formation of tetravalent bromine as a result of the reduction of bromate ions by radiolytically produced hydrated electrons and hydrogen atoms has been investigated in the iodide-bromate system. BrO 3...
Halogenations involve the use of reactive and toxic halogens (X2) or hydrogen halides (HX). Chemical halogenations are fast and exothermic, but with little regio- or stereoselectivity. By doing halogenation reactions with halide anions, O2 or hydrogen peroxide (H2O2) as oxidants and vanadium- ...

When an additional electron-withdrawing group is present on the alpha-carbon, enolates become much easier to form. Enolates are nucleophiles and have many useful reactions with electrophiles. In this post we will cover the reactions of enolates with H+ , halogens, and simple electrophiles. ...
Carbon as a catalyst in oxidation reactions and hydrogen halide elimination reactions Carbon catalyses many reactions, mainly oxidation reactions with oxygen and with halogens, e.g. SO 2 + 1 20 2 → SO 3, or CO + Cl 2→ COCl 2. It is known, ... HP Boehm,G Mair,T Stoehr,... ...
1. Write the names of the halogens in order of reactivity, from the most reactive to the least. 2. Compare your reactivity series with Group 7 in the Periodic Table – what do you notice? 3. What results might you get if fluorine water and potassium fluoride were in the experiment too...

<p>To determine the correct order of increasing leaving group capability of the given anions (I: CI^(-), II: CH₃O^(-), III: CH₃S^(-), IV: I^(-)), we need to analyze their acidity and basicity. The leaving group ability is directly related to the ac
If the ion pair formed by alkene protonation collapses to product faster than rotation takes place, syn addition occures because the proton and halide ion are initially on the same face of the molecule. 18 2.2 Addition of Halogens Alkene chlorinations and brominations are very general reactions,...
