plzzzzz give me full solution of this.

Answer 1

this question is based on valance bond theory .

1) s + s both are sphereical shape so, no directional bond form , it means sigma bond exist here .

s + px , s + py and s + pz all have unidirectional bond . here also form sigma bond .

px + px , py + py , and pz + pz all overlap in x -axis , y -axis , z -axis respectively. so, here head on overlapping exist .
so, sigma bond will bare form by this

px + px in y or z -axis side-wise overlapping so, pi-bond will be form

py + py in x or z -axis also form pi -bond

pz + pz in x or y -axis also form pi-bond
