Answer the following on a separate sheet of paper. 1. Using the data collected for PF, SF, and CIF, what structural comments can be made about molecules with more than four groups (charge clouds) around the central atom? 2. Select which structure is preferred and discuss why? SC 3. To assess the stability of the axial versus equatorial positions for a trigonal bipyramidal structure, a computer program was used to determine the energy to assess SF, with the lone pair...
Complete the following table for a molecule of COCI2. You can assume that all atoms obey the octet rule.(a) Draw the Lewis structure. Show ALL valence electrons. (d) Draw a valid wedge-and-dash Total number of valence (b) What is the molecular geometry around the central atom? (e) Add dipole moments for each polar covalent bond.(c) What is the bond angle predicted by the VSEPR model? (e) Is the molecule polar or nonpolar? If polar, draw the net dipole moment. If nonpolar, briefly explain why.
Shown below is the partial structural formula for the amino acid L-cysteine, HSCH2(NH2)CHCOOH. The dotted lines represent connectivity of the atoms, but the structure does not show the correct bond orders (single, double, etc.). Complete the following activity for L-cysteine. ННО 2 4 H N-H 1. Write the name and chemical formula of the molecule shown above. 2. Determine the total number of valence electrons in the molecule. 3.

Second Week: A closer look at molecular geometries and polarity. This part of the laboratory will make use of the PhET simulation for molecule polarity. On the phet.colorado.edu website, select "Play with Simulations." Now, choose "Chemistry" in the left options of simulations, and then select the "Molecule Polarity" simulation. Choose the "Three Atoms" simulation. When the simulation loads, in the "view" menu, choose to display the bond dipoles, molecular dipoles, and partial charges. Questions Water, H2O 1. Draw the Lewis...

Carbon tetrachlorida CCl4, bp-77 celcius, is a very potent ozone depleter. An unethical grad student decides to dispose of 100mL (1mole) of carbon tetrachloride by boiling it off into the atmosphere. Estimate the percentage of C-Cl bonds in the original molecules that would be broken by this boiling process. Compare the strength of the dipole-dipole attraction and induced dipole-induced dipole attaction (London or dispersion forces) to each other and for each effect, draw the structure of a molecule whose boiling...
