Question

which of the following combination does not give sigma molecular orbital (assume z Axis as internuclear axis)​

Answer 1

Answer:

the combination does not give sigma molecular orbital is2px and 2py

Answer 2

Px and Py molecular orbital do not give sigma molecular orbital.

Explanation:

• Px and Py molecular orbital do not show sigma molecular orbital
• Similar sub orbitals form molecular orbitals.
• These orbitals have equal energies and here molecular orbitals formation is possible.
• Thus Px and Py are dissimilar orbitals they have different energy levels and hence do not form sigma orbitals.
• Px, Py and Pz orbital are formed as suborbital.
• Sigma bonds are formed between orbitals of equal energy and axial overlapping.
