What is the structure of benzene?
What is the structure of benzene?
A six-membered ring composed of six carbon atoms, each bonded to one hydrogen atom and two other carbon atoms. Each carbon atom has a double bond and is sp² hybridized, resulting in a planar structure.
What is the molecular formula of benzene?
What is the molecular formula of benzene?
The molecular formula for benzene is C6H6, indicating six carbon atoms and six hydrogen atoms.
Why is benzene considered stable?
Why is benzene considered stable?
Benzene has a unique stability due to the delocalization of its π electrons. It doesn't undergo typical addition reactions like unsaturated hydrocarbons do.

Study Notes
Benzene and Aromatic Compounds
- Benzene is a ring structure containing 6 carbon atoms.
- Each carbon atom in the ring is bonded to one hydrogen atom and two other carbon atoms.
- Each carbon atom exhibits sp² hybridization and one double bond.
- The molecular formula for benzene is C₆H₆.
- Unlike alkenes, alkynes, and dienes, benzene does not readily undergo addition reactions.
- Kekulé proposed that benzene is an equilibrating mixture of two structures, each with alternating single and double carbon-carbon bonds within a six-membered ring.
- In Kekulé's model, the bonds between carbon atoms are sometimes single and sometimes double.
- Benzene's structure is more accurately represented by delocalized π-bonds.
