Expert Answer

Step 1

The addition of HX to alkynes takes place by the Markonikov’s addition in which the hydrogen gets bonded to that carbon which has more number of hydrogen atoms, while the halogen is added to the carbon having less number of hydrogen atoms.

Step 2

With the excess amount of HX, an anti-addition takes place which results in the formation of a geminal dihaloalkane.

Step 3

The given reaction takes place as f...
