For diatomic molecules, the correct statement(s) about the molecular orbitals formed by the overlap of two 2pz2{p}_{z} orbitals is(are)For diatomic molecules, the correct statement(s) about the molecular orbitals formed by the overlap of two 2 p _ z

Options

  1. Aσ\sigma orbital has a total of two nodal planes.
  2. Bσ∗{\sigma}^{*} orbital has one node in the xzxz-plane containing the molecular axis.
  3. Cπ\pi orbital has one node in the plane which is perpendicular to the molecular axis and goes through the center of the molecule
  4. Dπ∗{\pi}^{*} orbital has one node in the xyxy-plane containing the molecular axis.

Correct answer

A. σ\sigma orbital has a total of two nodal planes.

Step-by-step solution

When this orbital combine along the internuclear axis then σ\sigma orbital is formed while this orbital approach each other parallel to each other and perpendicular to the internuclear axis π\pi orbital is formed.
