Molecular orbital theory?

Hello dear community, I have a question about molecular orbital theory. According to it, when two atomic orbitals bond, two molecular orbitals are created: a bonding orbital and an antibonding orbital. My textbook states: And now my question: Do the bonding and antibonding MOs occur simultaneously, and one of them is simply unoccupied, or does…

Bonding relationships amino acid EPA, molecular orbital theory?

Hello, I have my advanced chemistry exam coming up soon and wanted to ask how amino acids are generally hybridized according to valence bond theory. My teacher said the amino group is sp3 hybridized, meaning the nitrogen atom, and thus it would be tetrahedral, but why? I was thinking more pyramidal planar due to the…

How can He2+ bonding be explained using the VB theory alone?

I'm currently learning about covalent bonds using the corresponding VB and MO theories, and I'm wondering how the VB theory would explain the bonding in He2+? With MO theory, one could simply say that the bonding sigma orbital is occupied by an electron pair and the antibonding sigma orbital is occupied by the third electron,…
