Title: Reactions of Dienes with HBr

Instructions:
Draw the major 1,2- and 1,4-addition products formed when this diene reacts with HBr. Do not include any byproducts formed.

Chemical Structure:
The image depicts a six-membered diene with two double bonds, one at the top left and another at the top right corner of the hexagonal structure. 

Reaction Details:
- Reactant: Diene (illustrated in the structure)
- Reagent: HBr (1 equivalent)

Outcome:
1. Draw 1,2-Product
   - The space provided indicates where the 1,2-addition product should be drawn. This product involves the addition of HBr across one of the diene's double bonds resulting in the formation of a bromoalkene.
   
2. Draw 1,4-Product (Note: not explicitly requested in the image but inferred by the initial instruction)
   - Similarly, a 1,4-addition would involve the addition of HBr across the diene, resulting in a product where the H and Br are added on the first and fourth carbons, respectively.

This exercise illustrates the concept of regioselectivity in addition reactions involving conjugated dienes.
