WebBromine definition, an element that is a dark-reddish, fuming, toxic liquid and a member of the halogen family: obtained from natural brines and ocean water, and used chiefly in the … WebAug 21, 2024 · The problem is that concentrated sulfuric acid is an oxidizing agent, and as well as producing hydrogen bromide or hydrogen iodide, some of the halide ions are oxidized to bromine or iodine. Phosphoric acid does not have this ability because it is not an oxidant. The acidity of the hydrogen halides Hydrogen chloride as an acid WebThis is because the enol is so reactive toward bromine that it never has a chance to reverse step 2, i.e., it is not protonated by hydronium ion to give back the conjugate acid of the carbonyl compound. So bromine reacts much more rapidly than does hydronium ion with the intermediate enol. Once formed, the enol always goes on to brominated product. lakes in colorado to live on
