Molecular orbitals for water as determined by symmetry (SALCs) for the C2v point group. Answer (1 of 5): Qualitative Molecular Orbital is not the best theory to explain geometry of molecules; instead, the empirical geometry is assumed to compute linear combinations of atomic orbitals. For qualitative purposes, VSEPR (Valence Shell Electron Pair Repulsion) theory gives better predict...

Molecular orbital theory describes the distribution of electrons in molecules in much the same way that the distribution of electrons in atoms is described using atomic orbitals. Using quantum mechanics, the behavior of an electron in a molecule is still described by a wave function, Ψ, analogous to the behavior in an atom.Just like electrons around isolated atoms, electrons around atoms in ... Sep 04, 2021 · Obtain the molecular orbital diagram for a homonuclear diatomic ion by adding or subtracting electrons from the diagram for the neutral molecule. This switch in orbital ordering occurs because of a phenomenon called s-p mixing. s-p mixing does not create new orbitals; it merely influences the energies of the existing molecular orbitals. the lowest energy molecular orbital of water, which consists primarily of the 1S orbital from the oxygen. The displayed orbital can be made to look like orbital #1. in Fig. 2. by changing the material to “Transparent” and the coloring method to “ColorID”. For older computers and those without For two equivalent bonds (as the O-H bonds here are expected to be) with a bond angle θ, the hybridization of the localized bond orbital is given by s p λ where. λ = − 1 cos. ⁡. θ. Applying this to the known bond angle of water, we find that the O-H bond orbitals are ≈ s p 4, that is, 80% p and 20% s. So they are slightly more p in ...
