CO 11: Describe and interpret the three-dimensional shape and polarity of covalently bonded structures. Use the Lewis structure below to answer the following questions: a) Identify the most polar bond in the structure. Answer by labeling partial positive ($\delta^+$) and partial negative ($\delta^-$) charges on the atoms for the most polar bond on the structure to the right. $H^{\delta^+} \quad :O^{\delta^-} \quad$ $\quad H-C-H \quad$ $\quad H-C-H \quad$ $\quad H \quad$ b) For electrostatic potential maps are shown. Which of these have a dipole moment? Circle any/all that apply. 1 2 3 4 c) Match each electrostatic potential map from part b) to one structural formula. The orientation may not be the same, check for polarity and shape! List by number. $\quad H \quad O \quad H$ $\quad H-C-C-C-H \quad$ $\quad H \quad H \quad H$ $\quad H-C-C-O-H \quad$ $\quad H \quad H \quad$ 1 3 $\quad H \quad H \quad$ $\quad H-C-C-F \quad$ $\quad H \quad H \quad$ 4 $\quad Cl \quad$ $\quad H-C=C \quad$ $\quad Cl \quad H \quad$ 2 d) Consider the Lewis structures shown here. Label each as either polar or nonpolar. $:Cl:$ $H-C-H$ $:F:$ $:F-B-F:$ $H$ $:F:$ $:F-S-F:$ :F:$ Nonpolar Polar Nonpolar

Which of the following statements is correct? A change in demand or supply can only be caused by a change in price. A simultaneous decrease in demand and increase in supply will result in an increase in equilibrium price and uncertain effect on quantity.
