H2o mo theory
WebQuestion: Consider the series of hydride molecules LiH,BeH2,BH3,CH4,NH3,H2O, and HF. For each nolecule, would the covalent single bond to the hydrogen atom be better described using simple VB or MO theory? For this series, identify molecular properties that might best be lescribed by VB theory. Recall that VB theory underestimates and MO theory ... WebJul 14, 2024 · In H X 2 O you expect oxygen to follow the octet rule, hence there will be four electron pairs around it, and it predicts a generally tetrahedral structure of the molecule. The angle for these shapes is about 109 ∘. Since hydrogen is more electronegative than no ligand, Bent's rule predicts a smaller angle than that.
