WebFirst, the bond connected with the leaving group and the bond connected with the H must be in the same plane to allow the proper orbital overlapping of the two carbons in the formation of the π bond of the alkene product. Second, the leaving group and H must be in anti-position to each other. Web1:00. I would think that the double carbon-oxygen bond would be pulled at by the oxygen, giving it a slight negative charge, and the hydrogen-oxygen bond would be pulled at by the oxygen, giving the hydrogen a slight positive charge. These two … Here's the general reaction for a hydrohalogenation. You have an alkene, …
