Q3 : Week 5 – 3/5 – 3/9
______________________________________________________ Jump to: Monday Homework 3/6 – Monday – A Day – 2/3a Lab, 4
a) To introduce MO theory, a non- valence bond theory.
b) To complete a MO diagram.
c) To compare BO, bond lengths, and bond energies by MO diagrams.
1. Potential Energy Internuclear distance Diagram
Complete the Potential Energy Internuclear distance Diagram Use diagram to explain Bond Energy and Bond Length with chart posted this week.
3. Lattice Energy – Lets Remember that we have ionic compounds that are in the mix. They are ions attracting themselves in a crystal lattice and are not part of the hybridization or polarity discussion. Because all ionic compounds are solids (in crystal arrangements) at STP we use lattice energy to describe their stability or strength of ionic character. Much like we use the difference of electronegativity for the dipole moment of each polar bond in covalent (molecular) compounds.
5. Review the need for another theory other than the valence – bond theories that we have been studying
