Question

The conditions for the combination of atomic orbitals to form molecular orbitals are stated below. Mark the incorrect condition mentioned here.

• A. The combining atomic orbitals must have nearly same energy
• B. The combining atomic orbitals must overlap to maximum extent
• C. Combining atomic orbitals must have same symmetry about the molecular axis
• D. Pi $(\pi)$ molecular orbitals are symmetrical around the bond axis

Answer 1

Answer: (D)

Pi $(\pi)$ molecular orbitals are symmetrical around the bond axis

Answer 2

Sigma molecular orbitals are symmetrical around the bond axis while pi molecular orbitals are not symmetrical.
