Why does type of overlap given in the following figure not result in bond formation?

उत्तर

In the first figure given above, the area which is under ++ overlapping is equal to the area under +– overlap. Both the overlaps cancel out with each other as they are oppositely charged. Due to cancelling out of the overlaps the net overlap will be zero.

In the second figure given above, both the p-orbitals are perpendicular to each other. Due to the `p_x, p_y` orbitals being perpendicular with each other, no overlap will be possible.
