3-77 Ozone, O3, is an unstable blue gas with a characteristic pungent odor. In an ozone molecule, the connectivity of the atoms is O−O−O and both O−O bonds are equivalent.
(a) How many valence electrons must be present in an acceptable Lewis structure for an ozone molecule?
(b) Write two equivalent resonance contributing structures for ozone. Be certain to show any positive or negative charges that may be present in your contributing structures. By equivalent contributing structures, we mean that each has the same pattern of bonding.
(c) Show by the use of curved arrows how the first of your contributing structures may be converted to the second.
(d) Based on your contributing structures, predict the O−O−O bond angle in ozone.
(e) Explain why the following is not an acceptable contributing structure for an ozone molecule:

- 3-119 Perchloroethylene, which is a liquid at room temperature, is one of the most widely used solvents for commercial dry cleaning. It is sold for this purpose under several trade names, including Perciene®. Does this molecule have polar bonds? Is it a polar molecule? Does it have a dipole?arrow_forward3-58 In Section 2-3B, we saw that there are seven diatomic elements. (a) Draw Lewis structures for each of these diatomic elements.

- 3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can. (a) How many valence electrons are present in a molecule of N20? (b) Write two equivalent contributing structures for this molecule. The connectivity in nitrous oxide is NNO.
