Question

16. Which of the following may result in zero overlapping? (Assume z-axis is internuclear axis)
(1) S+ S
(2) s+ Pz
(3) P,+ P2
(4) P + Py​

Answer 1

Answer:

2)s+pz may result in zero overlapping

Answer 2

(4) $p_{x}+p_{y}$ will have zero overlapping.

Explanation:

• The overlapping of orbitals take place in those orbitals which have same symmetry and same energy.
• The orbital px is along the x-axis, and py is along y-axis.
• These two are along different axis, so they will have zero overlapping.
• Therefore, option (4) $p_{x}+p_{y}$ is correct.
