Would you expect the wavelength of maximum absorbance for [Cu (NH3) 4]2 + to be greater than or less than the wavelength of maximum absorbance for Cu (H2O) 62+? Explain

Why is oil unable to dissolve well in water? Water is polar and oil is nonpolar, which means they have no attraction for each other. Oil molecules are too large to fit between the closely spaced water molecules in the liquid state.
