Show and explain all work.
The absorption spectra of solutions containing Br2 are solvent-dependent. When elemental bromine is dissolved in nonpolar solvents such as hexane, a single absorption band in the visible spectrum is observed near 500 nm. When Br2 is dissolved in methanol, however, this absorption band shifts and a new band is formed. Account for the appearance of the new band. Is the 500 nm band likely to shift to a longer or shorter wavelength in methanol? Why? In your answers, you should show clearly how appropriate orbitals of Br2 and methanol interact.Explanation / Answer
