Consider the following flat drawing of methane (CH4) . a. What is HCH bond angle implied by this drawing if you assume it is flat? b. Are the electron domains of this flat CH4 spread out as much as possible? c. Use model materials to make a model of CH4 (methane). If you assembled it correctly, thefour bonds (bonding electron domains) of your model will be 109.5° apart. d. In which representation, the drawing above or the model in your hand (circle one) are theH’s of CH4 more spread out around the central carbon? e. Confirm that your model looks like the following drawing. The wedgebond represents a bond coming out of the page, and the dash bondrepresents a bond going into the page f. You will often see methane drawn as if it were flat (like on the previous page). Why is thismisleading, and what is left to the viewer’s imagination when looking at such a drawing?
For each of the following molecules, complete the Lewis structure and use the VSEPR model to determine the bond angles around each central atom. Note that the drawings are only skeleton structures and may depict the angles incorrectly.

Use VSEPR theory to predict the shape of this molecule (POC13) and indicate any deviation from the bond angle(s) expected from a regular arrangement of repulsion axes. Show all the steps took to arrive at answer 4 to five sentences
Summarize LCAO–MO Theory?
Ozone (O3) has a nonzero dipole moment. In the moleculeof O3, one of the oxygen atoms is directly bonded to theother two, which are not bonded to each other.(a) Based on this information, state which of the following structures are possible for the ozone molecule:symmetric linear, nonsymmetric linear (for example,different OUO bond lengths), and bent. (Note: Evenan OUO bond can have a bond dipole if the twooxygen atoms are bonded to different atoms or if onlyone of the oxygen atoms is bonded to a third atom.)(b) Use the VSEPR theory to predict which of the structures of part (a) is observed.
The molecule shown below is called furan. It is represented intypical shorthand way for organic molecules, with hydrogenatoms not shown, and each of the 4 vertices representing acarbon atom. (a) What is the molecular formula for furan? (b) How manyvalence electrons are there in the molecule? (c) What isthe hybridization at each of the carbon atoms? (d) Howmany electrons are in the π system of the molecule? (e) TheC¬C¬C bond angles in furan are much smaller than thosein benzene. The likely reason is which of the following: (i) Thehybridization of the carbon atoms in furan is different fromthat in benzene, (ii) Furan does not have another resonancestructure equivalent to the one above, or (iii) The atoms in afive-membered ring are forced to adopt smaller angles than ina six-membered ring.
