Question

Atoms Q and T are interacting to form bonds (o, T). The compound formed is not necessarily diatomic. If Z-axis is taken the internuclear axis, the correct statement(s) regarding the formation of a bond is​

Answer 1

Answer:

s and py

px and dyz

px and py

All of these

Answer :

D

Solution :

To obtain a bonding MO (with a concentration of electron density in between the nuclei), the signs (symmetry) of the lobes which overlap must be the same. Similarly, for antibonding MOs, the signs of the overlapping lobes must be different.

In the combination shown above, any stabilization which occurs from overlapping + with + is destabilized by an equal amount of overlap of + with −. There is no overall change in eneryg, and this situation is termed as nonbonding. Same is true for px and py combination as they are perpendicular to each other.
