SF6 ond Polarity and Molecular Polarity (Dipole Moments) PROCEDURE For each of the molecules below, do the following: Lewis Structures 1) Draw a Lewis dot structure. 2) D etermine whether additional resonance structures are needed to adequately de pict this molecule. Draw all major and minor resonance structures, if any. alence Shell Electron Pair Repulsion (VSEPR) Theory Giv the number of "electron domains" around the central bonding atom. 4 Give the electron domain geometry (sometimes called the orbital geometry.) 5)...
Draw three-dimensional depictions of the following molecules. For each molecule provide theoretical bond angles, shape, and electron group geometry (ie octahedral, tetrahedral, bent, etc.). For each molecule, provide all possible structural and geometric isomers. If the molecule/ion possesses resonance structures, draw all relevant structures? What is the point group of each structure? If the compound is chiral, draw its enantiomer. NiCl2(NH3)2 (tetrahedral) PCl2F3 NO3-

Consider BrF3 and answer each of the following questions: a) How many regions of high electron density surround the central atom? b) Give the AXmE, notation. c) What is the electron pair geometry? d) What is the molecular geometry? e) What are the bond angles? (approximate) f) Is this molecule polar? 2. Are the electronic geometry and molecular geometry always the same? Explain. 3. Can a molecule have polar bonds and not be polar? Use NF3 and...
1. Assign the point group to each of the following molecules below by identifying all of the mirror planes, inversion centers, and Ca rotation axes. CI M.C Br Br a. b. XeF4 ни Cо OC c. SF4 CO OC Fe C e.
Use a group theory analysis to assign point groups to the cis and all trans isomers of [MA2B2C2]; use the character tables associated with each to determine whether they are chiral or not.
Find and list all symmetry elements present in the molecules below, and assign a point group to each. Indicate the principal axis (z axis) on each drawing. Note: Different resonance structures involving p-bonds do not destroy symmetry elements. You can assume the highest level of symmetry depicted in the drawings.
