Of the compounds below,the one that requires the shortest wavelength for photoionization is ________. A)O B)O₂ C)NO D)N₂ E)They all require the same wavelength.

Question

Quizplus · Accepted Answer

The compound with the lowest ionization energy requires the shortest wavelength for photoionization. Since the compounds O and NO have smaller atomic radii and higher effective nuclear charge compared to NS, they exhibit higher ionization energy than NS. Among the given compounds, N₂ has the lowest ionization energy, and hence requires the shortest wavelength for photoionization.
