Considering x axis as the intermolecular axis, which of the following will not form sigma bond?

View answer and explanation

Correct option: D

\mathrm{2}{\mathrm{p}_y}\mathrm{ \,\,and\,\, 2}{\mathrm{p}_y}

Option D is correct. When the x-axis is the intermolecular axis,

2p_y

and

2p_y

orbitals will overlap sideways, forming a pi bond, not a sigma bond.
