The Total solution for NCERT class 6-12
Considering x-axis as the internuclear axiswhich out of the following will not form a sigma bond and why? (a) 1s and1s (b) 1s and 2px (c) 2py and 2py (d) 1s and2s.
2py and 2py orbitals will not aform a sigma bond. Taking x-axis as the internuclear axis, 2py and 2py orbitals willundergo lateral overlapping, thereby forming a pi (π) bond.
