                                    3.33 x 10-33 C m = 1 debyes —> 1 D
 
         need to show slide polar slide in bonding demo
         Bond polarity/molecule polarity PHET
 
3. Complete the polarity discussion with 
 
    a) showing overall dipole moments for the molecules in the homework 
    b) Polyatomic ion – Table E in presentation Lewis structures (model a couple)
    c) Identify hybridization and lewis structures that are PERIODICALLY similar. 
    
    e) Bond Energy – Bond Energy and Bond length discussion with table below:
Carbon – Carbon bonds, electronegativity in HF, HCl, HBr, HI. Why is HI strongest acid?
 
 – WATER VS CARBON DIOXIDE – The meaning of Life!
 
 used the PHET animation below to show the polarity, dipole moments of a 3 carbon system, linear first then bent with outside with same high EN. I compared that with COlewis dot structure and molecular orbital sketch to illustrate how we can determine polarity by understanding geometry of orbitals. Especially the fact that central lone pairs will cause the linear structure to bend.  Also pi bonding and sigma bonding review.
Bond Energy and length data:  
Bond energy = the energy needed to break bonds = Bonds are stable thus Bond energy is always positive.
 
Bond length = distance between nuclei of atoms in a bond. 
                              Stronger the bond, stronger the attraction to the electrons between the bonded atoms and
                              this will lead to a shorter bond length.
 
                                   Stronger the BOND Energy the shorter the BOND length!
     π (pi) bonding occurs with every multiple bond between 2 atoms but it does not double or triple the bond 
energy because π bonding contains electron density that IS NOT between 2 nuclei.  I often describe π 
bonding as bonds that are perpendicular to the 2 nuclei that are simultaneously attracting the electrons. 
This is weaker than if the electrons are located exactly between the 2 nuclei in σ (sigma) bonding.

3/9  –  Tuesday –  “D” Day – Homework – 
Formal charges/ resonance – 
1: We use formal charges to evaluate lewis structures so that we pick the most stable and realistic structure.  THIS IS WHAT TONIGHT’s HOMEWORK is on!
 
2: In resonance the formal charges will be the same for all elements except that they will be in different locations.  
3: Formal charges will  help verify the overall charge on polyatomic ions

Formal Charges NOTEs:
 
*Formal Charges will help us determine how many double bonded oxygen in more advanced structures (chlorate structures). we keep adding the double bonds till the central atom will become a formal charge of zero.  Remember that Formal Charges are “bookkeeping values”  that help us determine the most accurate Lewis Structure.  They are part of this valence bond theory that is not perfect in explaining or predicting the properties of all molecules but without experimental data you  MUST follow formal charge rules:
 
a: Best Lewis Structure will have the more atoms at or near zero (atoms are using their valence electrons in the drawn Lewis structures).
 
b.  If given a choice the most Electronegative Atom will have a negative value (that atom will gain the electron because of its larger coulombic attractions for electrons).
 
c.  If the formal charges stay constant for different Lewis Structures for the same molecule or ion then you have Resonance.
 
2.  Complete NO3-1 polyatomic i0n lewis structure and discuss resonance and introduce Bond Order.
                 Bond Order =     All the bonds in a molecule (pair of electrons between atoms)
                                                    All the regions in the Lewis Dot Diagram that have bonds.
 
Molecules with resonant structures have Bond orders that are decimals to show that the electrons are are delocalized throughout the entire molecule!!  This adds a little extra bond energy in every domain!
 
 
3. Expanded octets – Started back side of Formal Charges with Chlorate geometry 1718.pdf in class.
     add Bond orders, formal charge/ resonance 17 – 21 slides in Resonance Presentation

Coming this afternoon!
 
2: Watch the Hybridization lecture – sp3d, sp3d lecture below (expanded octets):
 
We learned today that elements in Row 2 can only have a max of 8 electrons shared (octet rule!).
So it makes sense if we have elements with a n number greater than 2 (beyond row 2) then we can have Lewis dot structures that have more than 8 for our central hybridized atoms.
 
3:  Then complete  the Hybridization identification worksheet 2 expanded octets.pdf and start this worksheet with another video that models the first few chemicals and then review with the key.
Use my lecture and the worksheets to figure out the new geometries of the 2 NEW hybrid families!

 3/11  – Thursday –  “B” Day – Homework – 
1. In the past I would have given you a quiz to complete in class.  This year I am eliminating the in person quiz to save the teaching valuable days.  I am asking that you complete both of these “quizzes” and review with either the key or if you are having major trouble use the videos below of me reviewing every problem.  All of these skills are required AP Chemistry skills.  Your initial work will not be graded BUT WILL BE COLLECTED after you review your work with my resources.  I have /will send you a link to a google doc to upload both of these “quizzes”.  
 
So if you just copy the key’s I have posted and upload them into the google doc I have sent you you will get 2 100 scores for these quizzes BUT please try to take them as if they were a quiz and see how you do. Then review with my resources below and upload your perfect quiz.
 
I will not accept MY KEY’s as your work! I know someone will try…

Period 2:
1.  Review of sp3d and sp3d2 expanded octets through quiz examples:
 
2. 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.
 
Potential Energy Internuclear distance Diagram.pdf
Although we say the bond angles of any sp3 hybridized molecule is 109.5 degrees that is not entirely true as the “Internuclear Distance of the electron lone pair will decrease if there is not a nucleus pulling it away from the central hybridized atom.   The hybrid orbitals that contain the lone pair(s) are thus closer to the other hybrid orbitals and thus these hybrid orbitals repel the bonded hybrid orbitals into a smaller angle.
 
Notice the water, with 2 lone pairs, decreases the bond angle more (105)than one lone pair of ammonia (107).  You do not need to know the exact bond angles of molecular geometries for the lone pair molecules but be aware of this and why.
 
Run through slides 36 – 39:
 
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.
3/12  –  Friday –  “C” Day – Homework:
1.   Complete the take-home test AND Upload this test by 12:00 noon Sunday.  After 12:00 noon I will lock the linked google doc that I have sent you and you will NOT be able to upload or EDIT from that point forward.  
 
I will open the video below that reviews the test so that you may study for the IN-Person Test Monday at 12:00 noon. 
 
We will take another another Bonding test Monday (in person) as we will be all together!
I will take the average of the 2 tests to count as one bonding test.
 
If some reason you cannot complete the first Bonding test ON Time this weekend I will just count your individual in person test Monday WITHOUT the take home.
 
Please read the test topics below for the take-home and the additional test topics for 2nd test Monday.

2.  Follow along with me on the backside of the Formal Charges with Chlorate geometry 1718.pdf worksheet to write the lewis diagrams of the polyatomic ions.  
 
– You will need the Formal Charges to guide you when to stop adding double bonds to the oxygens.
– We are have been using a valence – bond theory and we are now reaching its limitations in this structures
   How do we explain double bonds in these structures that have sp3 hybridization with no un-hybridized p       
   orbitals?   We cannot and thus we have reached the limit of what dots on a piece of paper can tell us.
   We blindly follow the rules of formal charges at this point.
