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

Options

  1. AMolecular orbitals obtained from 2px2 \mathrm{p}_{\mathrm{x}} and 2py2 \mathrm{p}_{\mathrm{y}} orbitals are symmetrical around the bond axis.
  2. BA π\pi-bonding molecular orbital has larger electron density above and below the internuclear axis.
  3. CThe π∗\pi^* antibonding molecular orbital has a node between the nuclei.
  4. DIn the formation of bonding molecular orbital, the two electron waves of the bonding atoms reinforce each other.

Correct answer

A. Molecular orbitals obtained from 2px2 \mathrm{p}_{\mathrm{x}} and 2py2 \mathrm{p}_{\mathrm{y}} orbitals are symmetrical around the bond axis.

Step-by-step solution

- According to molecular orbital theory, the sigma (σ)(\sigma) molecular orbitals are symmetrical around the bond-axis while pi (π)(\pi) molecular orbitals are not symmetrical. As zz-axis is taken as internuclear axis, 2px2 p_x and 2py2 p_y forms π\pi molecular orbitals, hence these are unsymmetrical around the bond-axis
