Considering x-axis as the internuclear axis which out of the following will not form a sigma bond and why? (a) 1s and 1s (b) 1s and 2p_x (c) 2p_y and 2p_y (d) 1s and 2s.

Ans : 2p_y and 2p_y orbitals will not a form a sigma bond. Taking x-axis as the internuclear axis, 2p_y and 2p_y orbitals will undergo lateral overlapping, thereby forming a pi (``\pi``) bond.
