Reagents such as can add across carbob-carbon double and triple bonds, with H forming a bond to one of the carbon atoms in the multiple bond and Cl, Br or OH forming a bond to the other carbon atom in the multiple bond. In some cases, two products are possible. For the major organic product, the addition occurs so that the hydrogen atom in the reagent attaches to the carbon atom in the multiple bond that already has the greater number hydrogen atoms bonded to it. With this rule in mind, draw the structures of the major product in each of the following reactions
