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?
- Use Figs. 4-54 and 4-55 to answer the following questions. a. Would the bonding molecular orbital in HF place greater electron density near the H or the F atom? Why? b. Would the bonding molecular orbital have greater fluorine 2p character, greater hydrogen 1s character, or an equal contribution from both? Why? c. Answer the previous two questions for the antibonding molecular orbital in HF.Ethylene oxide is an intermediate in the manufacture or ethylene glycol (antifreeze) and polyester polymers. More than 4 million tons are produced annually in the United States. The molecule has a three-member ring of two C atoms and an O atom. (a) What are the bond angles in the ring? Comment on the relation between the bond angles expected based on hybridization an d the bond angles expected for a three-member ring. (b) Is the molecule polar? Based on the electrostatic poten1ial map shown below. where do the neg-alive and positive charges lie in the molecule? Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms. The electrostatic potential map clearly to explain, the oxygen atom has more negative () charge and other side has less positive () charge, so this molecule is a more polar nature.State whether or not each of the following has a permanent dipole moment. a. b. c. d. e. f.
