WebbHell-Volhard-Zelinsky or HVZ for short is an important reaction of carboxylic acids. It is actually a two-step sequence rather than just a reaction. The first step makes an α-brominated acid bromide. Then, in the second step you “quench” the bromide from the first step to make either an acid or an ester. WebbIn chemistry, protonation is the addition of a proton to an atom, molecule, or ion, forming the conjugate acid. Some examples include the protonation of water by sulfuric acid: the protonation of isobutene in the formation of a carbocation: = the protonation of ammonia in the formation of ammonium chloride from ammonia and hydrogen chloride: … WebbAzide. In chemistry, azide is a linear, polyatomic anion with the formula N− 3 and structure −N=N+=N−. It is the conjugate base of hydrazoic acid HN3. Organic azides are organic compounds with the formula RN3, containing the azide functional group. [1] The dominant application of azides is as a propellant in air bags. hope in of mice and men
