Final answer:
Bromine (Br₂) is a diatomic molecule with a simple linear structure and a bond angle of 180°, due to having a single bond with no lone pairs according to VSEPR theory.
Step-by-step explanation:
The chemical bromine (Br₂) does not have a complex VSEPR structure as it is a diatomic molecule consisting of two bromine atoms bonded together.
According to the VSEPR model, since there are no lone pairs on the central atom (as it doesn't apply to homonuclear diatomic molecules like Br₂), the molecule adopts a linear geometry with a bond angle of 180°.
This is because there is only one region of electron density around each bromine atom due to the single bond they share, resulting in the maximization of their distance apart to minimize repulsion, similarly to the molecule BeF₂ which also has a linear structure due to two bonding pairs and no lone pairs.
