Resonance Hybrid Structure and Geometry of Benzene

Benzene is an aromatic compound with the molecular formula C₆H₆.
The resonance hybrid of benzene is a combination of two equivalent resonance structures, which depict alternating single and double bonds in the ring.
Instead of discrete single and double bonds, the resonance hybrid indicates that all six carbon-carbon bonds in benzene are equivalent and intermediate in length between single and double bonds.
This delocalization of π-electrons results in a symmetrical structure with equal bond lengths.

EXPLANATION:

The resonance hybrid structure of benzene forms a planar, cyclic arrangement of six carbon atoms.
Each carbon atom is sp²-hybridized, resulting in 120° bond angles, which ensures the structure is perfectly planar.
The six carbon atoms form a regular hexagonal geometry, where the delocalized π-electrons above and below the plane contribute to the stability of benzene.
This hexagonal geometry is a key feature of benzene's resonance hybrid structure.

Therefore, the resonance hybrid structure of benzene indicates hexagonal geometry, and the correct answer is Option 2.
