Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

See image below

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.
