WebBecause polar solvents stabilize the ground state more than the excited state, the change in energy increases with the polarity of the solvent. As the solvents become more polar, the light absorbed by this dye shifts from the low energy, long wavelength (red) to the high energy, short wavelength (violet) end of the spectrum. WebAug 17, 2024 · The polarity of a molecule is important because it gives an idea of the solubility of the molecules in solvents. The polar solvent dissolves polar solutes and nonpolar solvent dissolves nonpolar solutes. Why is chloroform a non-polar solvent? Chloroform is “nonpolar” because it has a low dielectric constant.
