Considering x-axis as the internuclear a | Class 11 Chemistry Chapter Chemical Bonding and Molecular Structure, Chemical Bonding and Molecular Structure NCERT Solutions

Question:

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 2px

(c) 2py and 2py

(d) 1s and 2s.

Answer:

Sigma bond is always formed between two half filled atomic orbitals along their inter- nuclear axis ,i.e the line joining the centers of the nuclei of two atoms (axial overlapping).

From the given data if we consider x axis as the internuclear axis 2py and 2py overlapping is not possible as both the 2py orbital will lie on y axis.While the other 1s, 2s, 2px all lie on X axis internuclear axis.
