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

Options

  1. Aσ orbital has a total of two nodal planes.
  2. Bσ * orbital has one node in the xz -plane containing the molecular axis.
  3. Cπ orbital has one node in the plane which is perpendicular to the molecular axis and goes through the cen
  4. Dπ * orbital has one node in the xy -plane containing the molecular axis.

Correct answer

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

Step-by-step solution

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