Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with
Sergeu [11.5K]

Answer:

sp^2

Explanation:

Hello,

The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are  sp^2-hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one s orbital and two p orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining p orbital from each carbon atom sticks out above and below the plane of the ring; these p orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.

Best regards.
