Molecular orbitals are formed by the overlap of suitable atomic orbitals from different atoms. Symmetry and energies of the overlapping orbitals and distance between the approaching atoms are crucial for the formation of molecular orbitals. For diatomic molecules, by convention, the internuclear axis is taken to be in the z-direction. Correct statement(s) is /are

Options

  1. AMolecular orbitals formed from 2 p _x orbitals are not symmetrical around the internuclear axis.
  2. B2 s and 2 p _z orbitals can overlap to form a bonding orbital.
  3. COverlap of two 2 p _x orbitals will always form a stronger bond than overlap of two 2 p _z orbitals.
  4. DLinear combination of two 2 p _z orbitals can produce a molecular orbital.

Correct answer

D. Linear combination of two 2 p _z orbitals can produce a molecular orbital.
