Question

Draw the Molecular orbital structure of C2 2+ along with its bond/theory explanation.

Answer 1

Answer: The phenomenon of s-p mixing occurs when molecular orbitals of the same symmetry formed from the combination of 2s and 2p atomic orbitals are close enough in energy to further interact, which can lead to a change in the expected order of orbital energies.

Answer 2

$\huge\bf\underline\mathfrak{Required\: Answer}$

• Molecular orbital theory is more powerful than valence-bond theory because the orbitals reflect the geometry of the molecule to which they are applied.

• But this power carries a significant cost in terms of the ease with which the model can be visualized.

• One of these orbitals is called a bonding molecular orbital because electrons in this orbital spend most of their time in the region directly between the two nuclei.

• It is called a sigma () molecular orbital because it looks like an s orbital when viewed along the H-H bond.

• Electrons placed in the other orbital spend most of their time away from the region between the two nuclei.

• This orbital is therefore an antibonding, or sigma star (*), molecular orbital.
