Check ALL that are true of VSEPR theory.     VSPER number of 4 groups can produce tetrahedral, trigonal pyramidal and bent shapes.     A double bond counts as 2 groups of electrons that need space.     both bonds and electron pairs on the central atom need space.     It is based on the concept that electrons stay as far apart as possible to minimize repulsions.

Mark the following statements as true or false. A molecule with very polar bonds can be nonpolar.  blank The electrons in a polar bond are found nearer to the more electronegative element.  blank Fluorine is very polarizable.  blank Covalent bonds are partially ionic because of polarizability of atoms.  blank Kr and Sr2- are isoelectronic.

1. Draw the best Lewis dot structure for the anion CCI in the correct molecular geometry [Include formal charges and lone pair electrons, and use dashed and solid wedge bonds if necessary 2. How many electron groups are present around the central atom and what is the electron group geometry? 3. What is the molecular geometry and ideal bond angles? 4. Is the molecule polar or nonpolar? If it is polar, draw a dipole moment arrow next to your structure to indicate the directionality of the dipole moment.
