MCQ
The incorrect statement regarding molecular orbital $(s)$ is
  • A
    If there is a nodal plane perpendicular to the internuclear axis and lying between  the nuclei of bonded atoms then corresponding orbitals is antibonding $M.O.$
  • B
    If a nodal plane lies in the inter-nuclear axis, then corresponding orbitals is $pi(\pi)$  bonding $M .O.$
  • C
    The $\sigma$ -bonding molecular orbital does not contain nodal planes containing  the ternuclear axis
  • ✓
    The $\delta$ -bonding molecular orbital possesses three nodal planes containing  the internuclear axis.
✓

Answer

Correct option: D.
The $\delta$ -bonding molecular orbital possesses three nodal planes containing  the internuclear axis.
d
The $\delta$ molecular orbital possesses $2$ nodal planes containing the internuclear axis.
