AIIMS 2018 Chemistry Molecular Orbital Theory MCQ Question

In molecular orbital theory, bonding molecular orbitals formed from the overlap of atomic orbitals exhibit a nodal plane, which is a region where the probability of finding an electron is zero. In the case of S and P mixing along the Z-axis, the Pₓ orbital has a nodal plane that prevents effective overlap with the S orbital, making the statement regarding their mixing incorrect. Other options are not provided, but typically, incorrect options may misrepresent the nature of orbital interactions or fail to recognize the significance of nodal planes in bonding scenarios. Understanding these concepts is crucial for predicting molecular geometry and bonding characteristics in compounds like H₂O and CO₂.
