Question

Assuming the bond direction to the z-axis, which of the overlapping of atomic orbitals of two atom (A) and (B) will result in bonding? (I) s-orbital of A and px-orbital of B (II) s-orbital of A and pz orbital of B (III) py-orbital of A and pz orbital of B (IV) s-orbital of both (A) and (B)
