Question

Please indicate which of the molecules in the attached image are chiral.

The image contains six different chemical structures:

1. **Structure 1**: A bicyclic compound with two fused benzene rings and a methyl (Me) group attached to each ring.

2. **Structure 2**: A cyclohexane ring with a methyl group attached. This structure also features a wavy line, indicating stereochemistry (racemic mixture), with another group extending from the ring.

3. **Structure 3**: A tetracyclic compound consisting of three fused cyclohexane rings and one cyclohexene ring with a double bond, forming a polycyclic aromatic hydrocarbon.

4. **Structure 4**: A linear hydrocarbon chain with two bromine (Br) atoms attached at different stereochemical configurations, represented by wedge-shaped bonds. These wedges indicate 3D orientation, showing one bromine going 'out' of the plane and the other going 'in'.

5. **Structure 5**: An octagonal ring with alternating double bonds (a cyclooctatetraene), also featuring two methyl (Me) groups attached at two non-adjacent carbon atoms.

6. **Structure 6**: An adamantane-like bicyclic structure with three methyl groups attached at equal intervals, showcasing the rigid and symmetrical nature of the carbon framework.

Each diagram provides insight into the stereochemistry and functional groups, which are vital for determining the chemical and physical properties of these molecules.
