Packet #2  AP Chemistry

Name:

Chapters 9 and 10

Electronegativity, Lewis electron dot formula, calculating enthalpy from bond energy, molecular shapes, polarity of molecules, molecular orbital theory, hybridization.

The Nature of Matter Standard 1: The student understands that all matter has observable, measurable properties. (SC.A.1.4) 1. knows that the electron configuration in atoms determines how a substance reacts and how much energy is involved in its reactions. 2. knows that the vast diversity of the properties of materials is primarily due to variations in the forces that hold molecules together. 3. knows that a change from one phase of matter to another involves a gain or loss of energy. 4. experiments and determines that the rates of reaction among atoms and molecules depend on the concentration, pressure, and temperature of the reactants and the presence or absence of catalysts. 5. knows that connections (bonds) form between substances when outer-shell electrons are either transferred or shared between their atoms, changing the properties of substances. Standard 2: The student understands the basic principles of atomic theory. (SC.A.2.4) 1. knows that the number and configuration of electrons will equal the number of protons in an elec-trically neutral atom and when an atom gains or loses electrons, the charge is unbalanced. 2. knows the difference between an element, a molecule, and a compound.

1.  Draw out a structures of  molecules that have sp,sp^2, sp^3, sp^3d and sp3^d^2 hybridizations.  Indicate polarity of molecule.  2.  Selt Test question worksheet 1-14.

The test will be on chapters 9 and 10.
