Pi (π) bond between two atoms is
Correct answer: D. Formed by parallel overlapping of atomic orbitals, and is weaker than sigma bond.
- A. Formed by axial overlapping of atomic orbitals, and is stronger than sigma bond.
- B. Formed by parallel overlapping of atomic orbitals, and is stronger than sigma bond.
- C. Formed by axial overlapping of atomic orbitals, and is weaker than sigma bond.
- D. Formed by parallel overlapping of atomic orbitals, and is weaker than sigma bond.
Explanation
Pi (π) bonds are formed by the parallel overlap of atomic orbitals that have electron density above and below the bond axis. Pi bonds are generally weaker than sigma bonds, which are formed by the head-on overlap of atomic orbitals. Covalent bond which is formed by parallel overlapping of the half-filled atomic orbitals of atoms is called pi bond. It is weaker than a sigma bond.

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.
