Chemical Bonding And Molecular Structure Ques 116
116. The angle between the overlapping of one $s$-orbital and one $p$-orbital is
[1988]
(a) $180^{\circ}$
(b) $120^{\circ}$
(c) $109^{\circ} 28^{\prime}$
(d) $120^{\circ} 60^{\prime}$
Show Answer
Answer:
Correct Answer: 116.(a)
Solution:
(a)

The overlap between $s$ - and $p$-orbitals occurs along internuclear axis and hence the angle is $180^{\circ}$.
