q3
Transcribed Image Text:Consider a N2 molecule in its first excited electronic state, that is, when an electron in
the highest occupied molecular orbital (HOMO) is promoted to the lowest unoccupied
molecular orbital (LUMO).
Identify the molecular orbital involved and sketch a diagram to show the
transition.
Compare the bond order and bond length of N₂* with N2, where the asterisk
denotes the excited molecule.
Is N₂* diamagnetic or paramagnetic?
When N₂* loses its excess energy and converts to the ground state N2, it emits a
photo of wavelength 470 nm, which makes up part of the aurora lights. Calculate
the energy difference between these level.

- A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of chloroform, ethanolamine, dimethyl sulfoxide, pentane, and carbon tetrachloride. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid chloroform density 1.5 g cm 3 ethanolamine 1.0 g-cm dimethyl sulfoxide 1.1 g cm pentane 0.63 g-cm carbon tetrachloride 1.6 g-cm Next, the chemist measures the volume of the unknown liquid as 0.688 L and the mass of the unknown liquid as 543. g. Calculate the density of the liquid. Round your answer to 3 significant digits. Given the data above, is it possible to identify the liquid?
