Question

Draw the structure for the major organic product of each of the following reactions. 

The image shows a chemical reaction diagram. 

- On the left side, there is a molecular structure representing a terminal alkyne. 
- An arrow points to the right, indicating the direction of the reaction.
- Above the arrow, the text reads: “HBr, peroxide (1 equivalent).”
- On the right side, there is a blank box labeled with the number "12."

This setup suggests the hydrohalogenation of an alkyne using hydrobromic acid (HBr) with a peroxide catalyst, following anti-Markovnikov's rule, which typically results in the addition of a bromine atom to the less substituted carbon atom of the alkyne. This is facilitated by the presence of a peroxide, initiating a radical reaction. The final product would be an alkene with a bromine substituent. The number in the box likely refers to a step or example number in an educational context.
