Question

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

Solution 1

2py and 2py orbitals will not a form a sigma bond. Taking x-axis as the internuclear axis, 2py and 2py orbitals will undergo lateral overlapping, thereby forming a pi (π) bond.

Solution 2

(c) It will not form a s-bond because taking x-axis as the intemuclear axis, there will be lateral overlap between the two 2py orbitals forming a Π -bond.

  Is there an error in this question or solution?
