The unhybridized "p" orbital in sp2 hybridization is:
Correct answer: C. Perpendicular to sp2 orbitals
- A. Parallel to sp2
- B. In the same plane
- C. Perpendicular to sp2 orbitals
- D. Out of plane
Explanation
In sp2 hybridization, the unhybridized "p" orbital is perpendicular to the plane formed by the three sp2 hybrid orbitals. The three sp2 hybrid orbitals lie in the same plane, forming an angle of approximately 120 degrees with each other. The unhybridized "p" orbital is oriented at a right angle to this plane.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
