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 $180^{\circ}$.
