All are true for pie-bond except:
Correct answer: A. pie-bond is formed from sp hybrid orbitals.
- A. pie-bond is formed from sp hybrid orbitals.
- B. pie-bond is formed by the parallel overlap of p-orbitals.
- C. pie-bond is formed when as sigma bond is already present.
- D. pie-bond is weaker than sigma bond.
Explanation
The statement that "pie-bond is formed from sp hybrid orbitals" is not true. A pie-bond is formed by the parallel overlap of unhybridized p orbitals. The s orbitals are not involved in the formation of pie-bonds.

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.
