Question

In halogenation reactions, why are halogens added on opposite sides of the compound?

because the reaction proceeds via free radical and the pi cloud holding the electron are directed away from each other
because of the formation of a halonium ion which sterically blocks one side of the compound thus the other side is open for attack
because the halogen should occupy both sides to accommodate the pi clouds
None of the above

Two equivalents of HCl are added to an alkyne, where do you expect to see the Cl atom?

The two Cl atoms will be distributed between the two Carbon atoms involved in the triple bond
The two Cl atoms forms a bond with the less substituted carbon
Both Cl atoms attach to one carbon, which is the more substituted one
A mixture of products are formed
