Total: 100 pts. 1. (8 pts) The neutral OH molecule is the most important oxidant in the troposphere, and has been a) b) implicated in certain ozone-destroying processes, which take place in the stratosphere. Electron affinity can be defined for molecules just as it is defined for single atoms. Write a
complete chemical equation representing the electron affinity of OH. Include all relevant state symbols ((3), (g), etc.) Assuming that the electron added to OH is entirely localized in a single atomic orbital on one
atom, identify which atom (O or H) is probably accepting the electron, and the n and l quantum
numbers of the atomic orbital that is doing so. The electron affinity of OH has been measured to be similar, but slightly more negative than the
electron affinity of single 0 atoms. Explain briefly why the electron affinity is similar but slightly
more negative. 2. (15 pts) Greenhouse gases contribute to global warming by absorbing infrared radiation. Only molecules with polar covalent bonds are possible to absorb infrared and contribute to the
greenhouse effect. Draw Lewis structures for the following molecules to determine whether or not
they would function as greenhouse gases. a) co d) 02
b) C02 e) H20
C) N2
