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 orbtials 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.
