Question

The neutral OH molecule has been implicated in certainozone-destroying processes which take place in

the upper atmosphere.

a) Electron affinity can be defined for molecules just as it isdefined for single atoms. Write a complete

chemical equation representing the electron affinity of OH.Include all relevant state symbols ((s), (g), etc.)

b) Assuming that the electron added to OH is entirely localizedin 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.

c) The electron affinity of OH has been measured to be similar,but slightly more negative than the

electron affinity of single O atoms. Explain briefly why theelectron affinity is similar but slightly

more negative.
