Which one of the following statements is incorrect related to Molecular Orbital Theory?

  1. A
    The π∗\pi^*π∗ antibonding molecular orbital has a node between the nuclei.
  2. B
    In the formation of bonding molecular orbital, the two electron waves of the bonding atoms reinforce each other.
  3. C
    Molecular orbitals obtained from 2Px2 \mathrm{P}_{\mathrm{x}}2Px​ and 2Py2 \mathrm{P}_{\mathrm{y}}2Py​ orbitals are symmetrical around the bond axis.
  4. D
    A π\piπ-bonding molecular orbital has larger electron density above and below the internuclear axis.

Correct answer: C

In the formation of $\mathrm{BMO}$, the two electron waves of the bonding atoms reinforce each other due to constructive interference. Molecular orbitals obtained from $$2 \mathrm{P}_{\mathrm{x}}$$ and $$2 \mathrm{P}_{\mathrm{y}}$$ orbitals are 'unsymmetrical' around bond axis.
