Hybridization And Geometry
Easychemistry
Hybridization of carbon in benzene is:
Select the correct option:
Solution
Incorrect! Answer:
sp2
- Definition of sp2: A central atom bonded to three other atoms with no lone pairs (or total steric number 3).
- Benzene Structure: C6H6. Each carbon atom is bonded to two other carbon atoms and one hydrogen atom.
- Orbital Usage: Three sp2 hybrid orbitals form three σ bonds around each carbon atom.
- π System: One unhybridized p-orbital remains on each carbon, perpendicular to the ring plane. These six p-orbitals overlap to form a delocalized π-electron cloud.
- Geometry: The result is a hexagonal planar structure with bond angles of 120∘.
