The H2O molecule.
a) Sketch the Lewis Dot structure.
b) Consider Hybridation of O's AOs. Draw the MO diagram that would result, or explain the TWO "H-O bonds." Be sure to label them on your diagram.
c) Label the MOs in your diagram. Are they sigma type or pi type interactions ? Bonding or Anti-bonding?
d) Let's now consider those other electrons in the molecule. They ( 4 electrons ) are not contributing or disrupting the bonds between H and O. We call these NON-Bonding electrons. Propose where they might fit into the MO diagram you just drew.
Homework Answers
c)
the molecular orbitals are labelled in the diagram and they are
sigma type interactions.
D) the non bonding electrons are place between bonding and anti bonding molecular orbitals in the molecular orbital diagram.
